Laser diodes continue to find new product applications as the lasing wavelength is pushed lower into the visible spectrum. The latest generation of Visible Laser Diodes (VLD's) operate at or near 635nm; this wavelength being equivalent to a helium neon gas laser, is highly visible to the human eye. VLD's in the range from 635nm to 690nm are replacing the traditional HeNe laser in many commercial products for good reasons: lower cost, compact size, and superior long-term reliability. Another intrinsic benefit, laser diodes are generally better suited for battery operated devices and other low voltage applications. While visible diodes are used extensively in commercial products, the near-infrared diodes are certainly not extinct. There are many applications still using lasers operating in the 780nm~850nm range as some machine vision systems and sensors are optimized for near-infrared light sources. The near-infrared diodes may not be considered as user-friendly as the VLD's; however, with the right tools, some of the inconveniences can be managed. In either case, visible or near-infrared, we stock a selection of the more popular laser diodes from several different manufacturers. . Hitachi: Optima is no longer using, selling, or supporting Hitachi laser diodes. As of April 99 there is some stock available, please refer to the Optima Laser Diode Close-Out Page for details.

Glossary, Application Notes, and FAQ's Terms Describing Laser Diode Absolute Maximum Ratings Terms Describing Laser Diode Electro-optical Characteristics Terms Describing Laser Diode Optical Characteristics FAQ's and Laser Diode Basics Question or Comments Ordering Information NOTES.PDF (61K) Click on the file name to download an Adobe PDF file covering this section. Terms Describing Laser Diode Absolute Maximum Ratings: Commonly used abbreviations are shown in parenthesis. Case Temperature (Tc) - Device temperature measured at the base of the package. Operating Temperature (Topr) - Range of case temperatures within which the device may be safely operated. Optical Power Output (Po) - Maximum allowable instantaneous optical power output in either continuous (CW) or pulse operation. Up to this point, there are no kinks in the optical power output vs. forward current curve. Important note: The optical power output specification is applicable to the bare laser diode - it does not allow for, or take into consideration, any optics that may be in the optical path, such as a collimating lens located between the laser diode and a power meter or other detector. Caution: Do not exceed the specified optical power output -- even an instantaneous (less than a nanosecond) application of excessive current or voltage may cause deterioration or catastrophic optical damage (COD) to the facets. Reverse Voltage (VR) - Maximum allowable voltage when reverse bias is applied to the laser diode or photodiode. For laser diodes with an internal monitor photodiode, the reverse voltage is specified for the laser diode as VR (LD) and for the photodiode as VR (PD). Storage Temperature (Tstg) - Range of case temperatures within which the device may be safely stored. Top of Page Laser Diode Application Notes - Optima Precision Inc. Terms Describing Laser Diode Electro-optical Characteristics: Commonly used abbreviations are shown in parenthesis. Automatic Power Control (APC) - Laser diode drive circuit based on a photodiode feedback loop that monitors the optical output and provides a control signal for the laser diode which maintains the operation at a constant optical output level. See additional information below on Drive Circuits and Operating in Constant Power Mode vs. Constant Current Mode. Automatic Current Control (ACC) or Constant Current - Laser diode drive circuit that operates the laser diode without a photodiode feedback loop, the laser diode is simply driven at constant current. The optical output will fluctuate as the laser diode temperature changes. See additional information below on Drive Circuits and Operating in Constant Power Mode vs. Constant Current Mode. Fall Time - Time required for the optical output to fall from 90% to 10% of its maximum value. Mode Hopping - As the temperature of the laser chip increases, the operating wavelength also increases. Rather than a smooth, continuous transition in the operating wavelength, the wavelength makes discrete jumps to the longer wavelength modes. The phenomenon is referred to as "mode hopping" or "mode jumps". Monitor Current (Im) - The current through the photodiode, at a specified reverse bias voltage, when the laser diode is producing its typical optical power output. Note: The manufacturers data may list specifications based on operation at lower optical output power than the devices absolute maximum rating. For example, the test condition might be 20mW for a diode with an absolute maximum optical output of 30mW. Operating Current (Iop) - The amount of forward current through the laser diode necessary to produce the specified typical optical output at a specified operating temperature. Operating Voltage (Vop) - The forward voltage across the laser diode when the device produces its specified typical optical output at a specified operating temperature. Photodiode Dark Current (ID(PD)) - The current through the reverse biased internal monitor photodiode when the laser diode is not emitting. Positional Accuracy (x, y, z) - Also referred to as emission point accuracy. These specifications define the positional accuracy of the laser diode emitter with respect to the device package. Delta x and delta y are measured as the planer displacement of the chip from the physical axis of the package. Delta z is measured perpendicular to the reference surface. Specifications may list both angular error expressed in degrees and the linear error in microns. Rise Time - Time required for the optical output to rise from 10% to 90% of its maximum value. Slope Efficiency (SE) or () - Also referred to as differential efficiency. This is the mean value of the incremental change in optical power for an incremental change in forward current when the device is operating in the lasing region of the optical power output vs. forward current curve. Threshold Current (Ith) - The boundary between spontaneous emission and the stimulated emission shown on the optical power output vs. forward current curve. Below the threshold current point, the output resembles the incoherent output from a LED; at or above the specified threshold current, the device begins to produce laser output. Once past the threshold point, stimulated emission is achieved and the optical output increases significantly for a small increase in forward current. Laser Diode Application Notes - Optima Precision Inc. Wavelength (p) - The wavelength of light emitted by the laser diode. For a single mode device, this is the wavelength of the single spectral line of the laser output. For a multi-mode device, this is the wavelength of the spectral line with the greatest intensity. Top of Page Terms Describing Laser Diode Optical Characteristics: Commonly used abbreviations are shown in parenthesis. Aspect Ratio (AR) - The ratio of the laser diode's divergence angles, (perpendicular) and // (parallel). A diode with a 27 perpendicular divergence and a 9 parallel divergence has an elliptical beam with an aspect ratio of 3:1. Please refer to the laser diode mounting kit page to see the difference between a nearly circular beam and the typical elliptical beam. Astigmatism (As) or (As) - The laser beam appears to have different source points for the directions perpendicular and parallel to the junction plane. The astigmatic distance is defined as the distance between the two apparent sources. A laser diode with a large amount of astigmatism must have the astigmatism corrected (or reduced) if the laser diode output is to be accurately focused - otherwise, the resulting focused beam will be astigmatic. Beam Divergence () and (//) - Also referred to as radiation angles. The beam divergence is measured as the full angle and at the half-maximum intensity point, known as Full Width Half Maximum or FWHM. Angular specifications are provided for both the perpendicular axis and parallel axis. Coupling Efficiency - The beam from the laser diode diverges as defined by the beam divergence specification. In coupling the laser diodes widely divergent beam into a lens or other device such as a fiber, the result is typically less than 100%. Coupling efficiency is defined as the percentage of total power output from the laser which effectively enters the external device (i.e. a lens or fiber). Far Field Pattern (FFP) - Intensity profile of the beam when measured at a distance from the front facet of the laser diode chip. Multimode Diodes - Laser diodes have either single or multiple longitudinal modes. For a multimode laser diode the emission spectrum consists of several individual spectral lines with a dominant line (line with the greatest intensity) occurring at the nominal wavelength of the device. Multimode laser diodes are often desirable as problems with mode hops are suppressed - consequently, multimode diodes generally have a better signal-to-noise ratio. Near Field Pattern (NFP) - Intensity profile of the beam when measured at the front facet of the laser diode chip. Numerical Aperture (NA) - The numerical aperture describes the ability of a lens to collect light from a source placed at its focal point. The maximum acceptance angle , is measured from the center axis of the cone of light to the outside or surface of the cone. Polarization Ratio - The output from a single cavity laser diode is linearly polarized parallel to the laser junction. Spontaneous emission with a random polarization and/or with a polarization perpendicular to the laser junction is also present. The polarization ratio is defined as the parallel component divided by the perpendicular component. For a diode operating near its maximum power the ratio is typically greater than 100:1. When operating near the threshold point, the ratio would be considerably lower as the spontaneous emission becomes more significant. Laser Diode Application Notes - Optima Precision Inc. Single-mode Diodes - Laser diodes have either single or multiple longitudinal modes. For a single-mode laser diode the emission spectrum consists of a single spectral line occurring at the nominal wavelength of the device. At output levels near threshold, multiple spectral lines may be present in the emission spectrum however, these secondary lines decrease as the output increases. Top of Page FAQ's and Laser Diode Basics: There are a number of precautions listed in the laser diode manufacturer's catalogs that should be observed when working with laser diodes. Below are a few points that might be helpful if you're new to this field: Safety Considerations - The laser beam emitted by the laser diode is harmful if aimed directly into the human eye. Never look directly into the laser beam or at any specular reflections of the laser beam. Electro-Static Discharge - Laser diodes are extremely sensitive devices and visible laser diodes (VLD's) tend to be the most sensitive type. The handling precautions outlined by the laser diode manufacturers are not overstated - good work habits require personal grounding straps and grounded equipment. ESD does damage laser diodes! Drive Circuits - Laser diodes should always be driven by either a Constant Current or Automatic Power Control (APC) circuit (the APC circuit may also be referred to as a Constant Power Mode circuit). For simplicity, an APC circuit is generally preferred, especially if the ambient temperature fluctuates. Typical circuits include slow-start or soft-start circuitry and provisions to ensure that spikes, surges, and other switching transients are eliminated. Regardless of type of circuit used, the drive current must not overshoot the maximum operating level - exceeding the maximum optical output for even a nanosecond will damage the mirror coatings on the laser diode end facets. A standard laboratory power supply is not suitable for driving a laser diode. Examples of the recommended drive circuits can be found in most manufacturer's laser diode data books. Unless you have prior experience with laser diodes and/or their drive circuits, this is not a place to reinvent the wheel - it can be very frustrating and expensive. Operating in Constant Power Mode vs. Constant Current Mode - The characteristics of a laser diode are highly dependent on the temperature of the laser chip. For instance, the wavelength of a typical GaAlAs diode will increase on the order of 0.25nm for a 1C rise in temperature. With a single mode diode, the change in wavelength may produce an undesirable effect known as "mode hops or mode-hopping". Other characteristics directly related to laser diode's operating temperature are; threshold current, slope efficiency, wavelength, and lifetime. Perhaps the most important characteristic is the effect of temperature on the relationship between the diode's optical output and the injection current. In this case, the optical output decreases as the operating temperature increases or, conversely the optical output increases as the operating temperature decreases. Without limits and safeguards built into the laser drive circuit, a wide swing in operating temperature could be catastrophic. However, there are two techniques commonly used to achieve a stable optical output from a laser diode: Constant Current mode combined with precise control of the diode's operating temperature is generally the preferred operating method. The constant current mode provides a faster control loop and a precision current Laser Diode Application Notes - Optima Precision Inc. reference for accurately monitoring the laser current. Further, in many cases the laser diode's internal photodiode may exhibit drift and have poor noise characteristics. If performance of the internal photodiode is inferior, the diode's optical output is likely to be noisy and unstable as well. Constant Current operation without temperature control is generally not desirable - if the operating temperature of the laser diode decreases significantly, the optical power output will increase and could easily exceed the absolute maximum. Constant Power or APC mode precludes the possibility of the optical power output increasing as the laser diode's temperature decreases. However, when operating in the constant power mode and without temperature control, mode hops and changes in wavelength will still occur. Further, if the diode's heat sink is inadequate and the temperature is allowed to increase, the optical power will decrease. In turn, the drive circuit will increase the injection current, attempting to maintain the optical power at a constant level. Without an absolute current limit thermal runaway is possible and the laser may be damaged and/or destroyed. Summary - for stable operation and maximum laser lifetime - temperature control and constant current operation is generally the best solution. However, if precise temperature control of the laser diode is not practical, then an APC circuit should be used. Drive Circuit Precautions - Even when a laser diode is driven by a suitable drive circuit, watch for possible intermittent or unreliable connections between the laser diode and the drive circuit. An intermittent contact in the photodiode feedback circuit will very likely destroy the laser diode. One not-so-obvious component to consider is the power control. If a potentiometer is used for setting the laser diode's power, evaluate the circuit design to determine the failure mode if the potentiometer's wiper breaks contact with the resistive element. Also, never use a switch or relay to make or break the connection between the drive circuit and the laser diode. Power Measurements - The output from a laser diode must be measured with an optical power meter or a calibrated, large area photodiode. It's not practical or safe to estimate a laser diode's output power based on the diode manufacturers minimum-maximum data as each diode has unique operating characteristics and manufacturing tolerances. Remember, once the laser diode is past the threshold point, stimulated emission is achieved and the optical output increases significantly for a small increase in forward current. Therefore, a very slight increase in drive current may cause the optical output to exceed the absolute maximum. Even with a visible diode, it's not feasible to judge the laser output by eye, an optical power meter or calibrated photodetector must be used. Also, be sure to include optical losses through any lenses or other components when making measurements or calculations. Laser Diode Application Notes - Optima Precision Inc. Operating Temperature and Heat Sinks - In most applications, laser diodes require heat sinks especially when operated continuously (CW). Without a heat sink the laser diode junction temperature will quickly increase causing the optical output to degrade. If the laser diode temperature continues to rise, exceeding the maximum operating temperature, the diode can be catastrophically damaged or the long term performance may degrade significantly. Generally, a lower operating temperature will help extend the diode's lifetime as the laser diode's reliability and MTTF are directly related to the junction temperature during operation. VLD's with lower wavelengths, i.e. ~635nm, appear to be more sensitive to temperature and users might consider thermoelectric cooling if operating in an environment with elevated ambient temperatures or if operational stability is a prerequisite. Also, using a small amount of a non-silicone type heat sink compound will improve thermal conductivity between the diode and heat sink. Lifetime note: If the laser diode's operating temperature is reduced by about 10 degrees, the lifetime will statistically double. Windows - Keep the laser diode window, and any other optics in the path, clean. Dust or fingerprints will cause diffraction or interference in the laser output that can result in lower output or anomalies in the far-field pattern. The window should be cleaned using a cotton swab and ethanol when necessary. Cyanoacrylate Adhesive Precaution - "Super glue" should not be used anywhere near laser diodes - or near any other optical component - outgassing may fog windows and other optical surfaces. The amount of fogging, or the time required to observe the fogging, varies with different products. If you're in doubt, test the adhesive over time at an elevated temperature and in a sealed container. For example, place a drop of the adhesive in question on a piece of glass, something like a microscope slide, then place the sample in a plastic bag and seal the bag.

Top of Page LDM 1100 KIT - Laser Diode Mount for O5.6mm and O9.0mm Diodes The LDM 1100 Laser Diode Mount is shown below in the left frame. This convenient mount facilitates mounting the popular O5.6mm and O9.0mm laser diodes on a standard optical bench post with a #8-32 thread (the post is not included in the kit). Often when we're working in the lab with various laser diodes and evaluating different optical assemblies, we find it very desirable to have the diode mounted in a heat sink/mount that provides direct access to the front of the diode. With unobstructed access to the diode's output, it's possible to position lenses or other optical components using a separate component holder and/or translation stage. Using the LDM 1100, the diode's base is firmly clamped against the heat sink surface and the diode's pins are accessible from the back side of the mount. A clearance hole on the back side of the mount permits using our laser diode socket (P/N 900-8060-000) which greatly improves reliability in connecting the diode with a drive cable. Note: The LDM 1100 KIT includes the heat sink/mount and mounting hardware for both O5.6mm and O9.0mm laser diodes.

Top of Page Laser Diode Mounting Kits, Heatsink and Collimating Lens Holder - Optima LDM 3300 KIT - Glass Asphere Lens with Large NA and Small Collimated Beam The LDM 3300 KIT is the newest addition to Optima's Laser Diode Mounting System. The compact cylindrical housing provides the essential heat sink for the laser diode and a fine-pitch thread for adjusting the collimating lens position in the z-axis - allowing the user to either collimate or focus the laser diode beam. The collimating lens used in the LDM 3300 kit is a diffraction limited, molded glass asphere with a large numerical aperture, Optima P/N 305-0464-780. With an NA of 0.5 the collimating lens will efficiently couple the output from most laser diodes. Also, this lens has a focal length that's slightly shorter than most of the Optima glass lenses - with a 4mm focal length, this lens creates a smaller collimated beam. The minimum working distance is approximately 6 mm from the front surface of the LDM housing. Using a Hitachi HL6312G laser diode as an example, a beam focused at the minimum working distance is approximately 20 x 9.6 microns (1/e2, with 20 microns being the parallel axis); a collimated beam 100 mm from the front surface of the housing is ~0.85 mm x 3.73 mm. When ordering this mounting kit for use with O5.6mm diodes, the part number changes to LDM 3356 KIT. P/N LDM 3300 KIT ... Unit price (Qty 1- 4) $54.60 each Top of Page LDM 3400 KIT - Interchangeable Apertures to Circularize an Elliptical Beam The LDM 3400 Laser Diode Mount is a unique design with a few features not found in the other Optima laser diode mounts. The 1/2-inch diameter cylindrical housing is essentially split into two sections; the back section holds the laser diode and the collimating lens. The front section holds a changeable aperture and provides the adjustment mechanism for positioning the collimating lens. The front section has a diamond knurl pattern on the outside diameter - to adjust the collimating lens position, just rotate the front section and the collimating lens moves precisely in the z-axis. The laser diode is firmly held in place by a threaded ring that sits on the back surface of the diode - increasing the metal-to-metal contact area and improving heat transfer. Multi-element collimating lens - The lens included with the LDM 3400 mount is the Optima P/N 336-1027-660 or 336-1027-785*. This is possibly one of the best general purpose collimating lens ever designed for visible and near-infrared diodes. When combined with the LDM 3400 mount, the assembly is simple and lens adjustment provides exceptional control. Please refer to the lens specifications page for detailed information. Interchangeable apertures - One technique used to "cleanup" or "circularize" a laser diodes elliptical beam is to pass the collimated beam through a small circular aperture. If the size of the aperture is small enough, the beam exiting the aperture will be circular - an obvious problem with this technique is a loss in optical power. However, most applications don't require a perfectly circular beam - somewhere between the diodes elliptical beam and a circular beam, there's usually an acceptable solution. Comparison of LDM 3400 KIT using the 4.83mm (largest) aperture and the 1.14mm (smallest) aperture: Laser Diode Mounting Kits, Heatsink and Collimating Lens Holder - Optima Figure 1 Focused beam 56.8 x 15.9 microns Aspect ratio of ~3.5 to 1 Figure 2 Focused beam 66.0 x 51.6 microns Aspect ratio of ~1.3 to 1 The two 3D figures shown above graphically illustrate the difference between an elliptical beam from a typical laser diode and a beam which has passed through a small aperture - effectively circularizing the beam. The laser diode used in these examples is the Hitachi HL6312G. The beam shown in figure 1 was collimated using the LDM 3400 KIT with the 4.83mm aperture installed. (The 4.83mm aperture has no effect on the beam as it is larger than the clear aperture of the collimating lens). The beam in figure 2 was collimated using the LDM 3400 KIT with the 1.14mm aperture installed. Both of the collimated beams were focused on the target sensor using a plano-convex lens with a 60mm focal length. The size of the focused spot in figure 1 is 56.8 x 15.9 microns with an aspect ratio of about 3.5:1. The size of the focused spot in figure 2 is 66.0 x 51.6 microns with an aspect ratio of about 1.3:1. (The figures are taken at the 1/e2 point and are listed as the parallel axis x perpendicular axis). Two additional points should be noted: When the beam is circularized with a small aperture, the focused spot will be larger than the focused spot which has not been clipped by an aperture. And with the larger diameter focused beam, the depth of field will increase. For a smaller focused beam consider the LDM 4200 KIT listed below. The LDM 3406 KIT and the LDM 3457 KIT includes 6 circular apertures in the following sizes - 1.14, 1.52, 2.03, 2.54, 3.05, and 4.83mm. The 4.83mm aperture is larger than the clear aperture of the collimating lens, and consequently, has no clipping effect on the beam. The smallest aperture (1.14mm) is approximately equal to the dimension of the collimated beam in the parallel axis (the minor axis of the elliptical beam). When the smallest aperture is imposed on the collimated beam, the output beam will be very close to circular (this depends on the diodes parallel axis divergence angle). The loss in power, as compared with the 4.83mm aperture, is approximately 50%. The larger diameter apertures may be used to cleanup a beam by removing side lobes and other artifacts without causing a significant loss in power. In any case, the range of aperture sizes supplied with the LDM 3406 kit allows the user to evaluate the tradeoffs between beam size and power loss. The LDM 3406 KIT is for use with 9mm diameter diodes; the LDM 3457 KIT is for use with 5.6mm diodes. Ready for Production - The LDM 3400 KIT and the LDM 3456 KIT includes one aperture - once you have determined the optimum size for the aperture, the kit is available in a lower cost production version with only one aperture. Special aperture sizes are available in production quantities; please contact the factory for a quote. The LDM 3400 KIT is for use with 9mm diameter diodes; the LDM 3456 KIT is for use with 5.6mm diodes. P/N LDM 3400/3456 KIT ...

Top of Page LDM 3500 KIT - Smaller Beam for Long Distance Applications The LDM 3500 KIT is similar to other laser diode mounts in the Optima product line - the housing provides a heat sink for the laser diode and a fine-pitch thread for adjusting the collimating lens position in the z-axis - allowing the user to either collimate or focus the laser diode beam. However, the collimating lens included in the LDM 3500 kit is a very high quality molded glass asphere with a long focal of 8mm, Optima P/N 305-8040-780. This lens creates a very good quality beam in applications where a smaller beam is required at longer distances. It can be used in bar code readers that need a longer depth-of-field and/or work at greater stand-off distances than the typical hand-held device. It's probably most useful in alignment systems and laser levels that project a beam in excess of a hundred feet. The minimum working distance is approximately 90 mm from the front surface of the LDM housing. Using a Hitachi HL6312G laser diode as an example, a beam focused at the minimum working distance is approximately 50 x 23 microns (1/e2, with 50 microns being the parallel axis); a collimated beam 100 mm from the front surface of the housing is ~1.68 mm x 5.30 mm. When ordering this mounting kit for use with O5.6mm diodes, the part number changes to LDM 3556 KIT. P/N LDM 3500 KIT ... Unit price (Qty 1- 4) $69.30 each Top of Page LDM 3600 KIT - Provides X-Y Alignment for Accurate Beam Pointing The compact cylindrical housing provides the essential heat sink for a O9mm laser diode and a precise three-axis adjustment system for positioning the collimating lens relative to the laser diode. During assembly, the lens is aligned in the x-y axis with the laser diode emission point and adjusted in the z-axis to collimate or focus the beam. The collimating lens included with this kit is a high quality, multi-element lens with a relatively large numerical aperture - Optima P/N 336-1027-660 for visible diodes, or the 336-1027-785 for near-infrared diodes. Please refer to the lens specifications page for detailed information. The minimum working distance is approximately 42 mm from the front surface of the LDM housing. Using a Hitachi HL6312G laser diode as an example, a beam focused at the minimum working distance is approximately 45 x 17 microns (1/e2, with 45 microns being the parallel axis); a collimated beam 100 mm from the front surface of the housing is ~0.98 mm x 4.06 mm. * The LDM 3600 KIT may also be special ordered with the 336-1027-140 lens which is AR coated for use with 1300 nm to 1550 nm laser diodes; please contact the factory for pricing and availability. P/N LDM 3600 KIT ... Unit price (Qty 1- 4) $89.25 each (Kit includes the collimating lens) Top of Page Laser Diode Mounting Kits, Heatsink and Collimating Lens Holder - Optima LDM 3700 KIT and LDM 3800 KIT - Easy to Assemble without X-Y Alignment Similar to the LDM 3600 except the lens is adjustable only in the z-axis, controlling the focus or collimation of the beam; there is no provision for moving the lens in the x-y axis. The collimating lens and laser diode are positioned to within 13 microns of the housing mechanical center line; however, due to misplacement of the laser die inside the laser diode package, the optical beam may not be coincident with the housing mechanical axis -- typically, the worse case pointing error is less than 17.5 mrad. The difference between the LDM 3700 KIT and LDM 3800 KIT is as follows: the mechanical details of the lens holder are slightly different and the LDM 3700 housing is 17mm in length, whereas the LDM 3800 housing is 18mm long. The same collimating lens is included with either mounting kit; it's a high quality, multi-element lens with a relatively large numerical aperture - Optima P/N 336-1027-660* for visible diodes, or the 336-1027-785* for near-infrared diodes. Please refer to the lens specifications page for detailed information. The minimum working distance is approximately 16 mm from the front surface of the LDM housing. Using a Hitachi HL6312G laser diode as an example, a beam focused at the minimum working distance is approximately 27 x 21 microns (1/e2, with 27 microns being the parallel axis); a collimated beam 100 mm from the front surface of the housing is ~0.98 mm x 4.06 mm. When ordering a mounting kit for use with O5.6mm diodes, the part number changes to LDM 3756 KIT or LDM 3856 KIT. Also, please specify which AR coating is required, -660 for visible diodes; or -785 for near-IR diodes. * The LDM 3700 or 3800 KIT may also be special ordered with the 336-1027-140 lens which is AR coated for use with 1300 nm to 1550 nm laser diodes; please contact the factory for pricing and availability. P/N LDM 3700 KIT ... Unit price (Qty 1- 4) $67.20 each (Kit includes the collimating lens) P/N LDM 3800 KIT ... Unit price (Qty 1- 4) $67.20 each (Kit includes the collimating lens) Top of Page LDM 3900 KIT - Molded Glass Aspheric Lens without X-Y alignment Similar to the LDM 3700 except the collimating lens provided is a molded glass asphere - Optima P/N 305-0065-780. This kit provides an excellent compromise between cost and performance -- something in between an assembly using the higher cost multi-element lens and a kit with a lower cost plastic lens. The optical performance of the lens is very good -- it creates a collimated beam which is slightly larger than a beam from the 336-1027 lens, resulting in a beam with less divergence and, consequently, a smaller beam at greater distances. Conversely, due to the longer focal length and larger clear aperture, this lens creates a smaller focused beam. Please refer to the lens specifications page for detailed information. The minimum working distance is approximately 21 mm from the front surface of the LDM housing. Using a Hitachi HL6312G laser diode as an example, a beam focused at the minimum working distance is approximately 24 x 10.5 microns (1/e2, with 24 microns being the parallel axis); a collimated beam 100 mm from the front surface of the housing is ~1.37 mm x 5.12 mm. When ordering this mounting kit for use with O5.6mm diodes, the part number changes to LDM 3956 KIT. P/N LDM 3900 KIT ...

Please refer to the lens specifications page for detailed information The minimum working distance is approximately 8 mm from the front surface of the LDM housing. Using a Hitachi HL6312G laser diode, a beam focused at the minimum working distance is approximately 19.5 x 8.6 microns(1/e2, with 19.5 microns being the parallel axis); a collimated beam 100 mm from the front surface of the housing is ~0.92 mm x 3.17 mm. When ordering this mounting kit for use with O5.6mm diodes, the part number changes to LDM 4056 KIT. P/N LDM 4000 KIT ... Unit price (Qty 1- 4) $43.70 each (Kit includes the collimating lens) Top of Page LDM 4100 KIT - Molded Glass Aspheric Lens with provision for X-Y alignment The compact cylindrical housing provides the heat sink for the laser diode and a precise three-axis adjustment system for positioning the collimating lens relative to the laser diode. During assembly, the lens is aligned in the x-y axis with the laser diode emission point and adjusted in the z-axis to collimate or focus the beam. The collimating lens included with this kit is the Optima P/N 310-0065-780, (this lens has the same spec's as the 305-0065-780, except the 310- version is in a special mount intended for this diode mounting kit). While the collimating lens is AR coated for 780nm, the lens works very well with both visible and near-infrared diodes. Please refer to the lens specifications page for detailed information. The minimum working distance is approximately 45 mm from the front surface of the LDM housing. Using a Hitachi HL6312G laser diode as an example, a beam focused at the minimum working distance is approximately 45 x 18.5 microns (1/e2, with 45 microns being the parallel axis); a collimated beam 100 mm from the front surface of the housing is ~1.37 mm x 5.12 mm. The LDM 4100 KIT is only available for O9.0mm diodes. P/N LDM 4100 KIT ... Unit price (Qty 1- 4) $77.20 each (Kit includes the collimating lens) Top of Page LDM 4200 KIT - Bi-aspheric Plastic Lens for Long Distance Applications This laser diode mounting kit is specifically designed to accept the Optima 300-0395-780 plastic aspheric collimating lens. Due to the relatively long focal length of the collimating lens, the housing is longer than most of the Optima laser diode mounts. With a long focal length (16mm) and small numerical aperture (NA=.14) this lens creates a relatively large diameter beam that's more circular than the output from a typical laser diode collimating lens. Also, the 300-0395-780 lens is a very high-quality injection molded plastic lens - this lens has been used in digital laser communication systems which are extremely sensitive to lens aberrations and diffraction patterns that can be misread as data when a beam sweeps across a detector. The only negative aspect of the lens might be the small NA - the coupling efficiency (or total transmission) for most visible laser diodes is just under 50%. Please refer to the lens specifications page for detailed information. Comparison of LDM 4200 KIT and the LDM 3700 KIT: Laser Diode Mounting Kits, Heatsink and Collimating Lens Holder - Optima Figure 1 -- LDM 4200 KIT Focused beam 19.9 x 13.1 microns Aspect ratio of ~1.5 to 1 Figure 2 -- LDM 3700 KIT Focused beam 54.8 x 15.2 microns Aspect ratio of ~3.6 to 1 The two 3D figures shown above graphically illustrate the difference between a nearly circular beam from the LDM 4200 KIT and the typical elliptical beam, in this case from the LDM 3700 KIT. The laser diode used in these examples is the Hitachi HL6312G. The beam shown in figure 1 was collimated using the LDM 4200 KIT and the beam in figure 2 was collimated using the LDM 3700 KIT which is typical of all Optima LDM kits using the 336-1027-xxx collimating lens. Both of the collimated beams were focused on the target sensor using a plano-convex lens with a 60mm focal length. The size of the focused spot in figure 1 is 19.9 x 13.1 microns with an aspect ratio of about 1.5:1. The size of the focused spot in figure 2 is 54.8 x 15.2 microns with an aspect ratio of about 3.6:1. (The figures are taken at the 1/e2 point and are listed as the parallel axis x perpendicular axis). Due to the long focal length, the minimum working distance is approximately 153 mm (6 inches) from the front surface of the LDM housing. If the application requires focusing at shorter distances, it would be best to collimate the output from the diode and then use a simple lens like a plano-convex to focus the beam. However, for reference we have measured the beam from the LDM 4200 kit using a Hitachi HL6312G laser diode; a beam focused at the minimum working distance is approximately 51.0 x 36.1 microns (1/e2, with 51.0 microns being the parallel axis); a collimated beam 100 mm from the front surface of the housing is ~3.38 mm x 4.65 mm. When ordering this mounting kit for use with O5.6mm diodes, the part number changes to LDM 4256 KIT. P/N LDM 4200 KIT ...

With a short focal length of 3.4mm, this lens provides at relatively small collimated beam. A large numerical aperture (NA) of 0.47 provides excellent coupling efficiency with most laser diodes. Please refer to the lens specifications page for detailed information. Laser Diode Mounting Kits, Heatsink and Collimating Lens Holder - Optima The minimum working distance is approximately 4 mm from the front surface of the LDM housing. Using a Hitachi HL6312G laser diode as an example, a beam focused at the minimum working distance is approximately 26.5 x 7.3 microns (1/e2, with 26.5 microns being the parallel axis); a collimated beam 100 mm from the front surface of the housing is ~0.74 mm x 2.89 mm. When ordering this mounting kit for use with O5.6mm diodes, the part number changes to LDM 4556 KIT. P/N LDM 4500 KIT ... Unit price (Qty 1- 4) $43.70 each (Kit includes the collimating lens) Top of Page LDM 5000 KIT - Low Wavefront Aberration, Larger Collimated Beam Unique housing design - This housing has a flat mounting surface perpendicular to the optical axis, ideal for attachment to a printed circuit board or thermal electric cooler. Four #2-56 threaded holes in the base facilitate mounting, alignment, and aiming - if the base is attached to a "soft" mount like a rubber o-ring or wave washer, the beam can be "pointed" by selectively adjusting the four mounting screws attached to the base. X-Y alignment - The laser emission point may be aligned with the lens optical axis by translating the diode in the x-y axis. While the lens is free to move in the z-axis (controlling focus or collimation) the lens does not rotate, minimizing lateral shift in the focused beam during the lens adjustment process. The collimating lens provided is a very high quality, diffraction-limited, multi-element lens with a large clear aperture and medium NA, Optima P/N 336-0965-780. With the larger clear aperture and excellent wavefront quality, this lens is intended for more demanding applications; such as laser diode instrumentation and/or long distance measurement applications. Please refer to the lens specifications page for detailed information. Broad range of lens adjustment - The minimum working distance is approximately 12 mm from the front surface of the LDM housing. Using a Hitachi HL6312G laser diode as an example, a beam focused at the minimum working distance is approximately 30 x 15.5 microns (1/e2, with 30 microns being the parallel axis); a collimated beam 100 mm from the front surface of the housing is ~1.52 mm x 5.71 mm. The LDM 5000 KIT is available in limited quantities and only for O9.0mm diodes. P/N LDM 5000 KIT ...

This convenient mount facilitates mounting the popular O5.6mm and O9.0mm laser diodes on a standard optical bench post with a #8-32 thread (the post is not included in the kit). Often when we're working in the lab with various laser diodes and evaluating different optical assemblies, we find it very desirable to have the diode mounted in a heat sink/mount that provides direct access to the front of the diode. With unobstructed access to the diode's output, it's possible to position lenses or other optical components using a separate component holder and/or translation stage. Using the LDM 1100, the diode's base is firmly clamped against the heat sink surface and the diode's pins are accessible from the back side of the mount. A clearance hole on the back side of the mount permits using our laser diode socket (P/N 900-8060-000) which greatly improves reliability in connecting the diode with a drive cable.

The compact cylindrical housing provides the essential heat sink for the laser diode and a fine-pitch thread for adjusting the collimating lens position in the z-axis - allowing the user to either collimate or focus the laser diode beam. The collimating lens used in the LDM 3300 kit is a diffraction limited, molded glass asphere with a large numerical aperture, Optima P/N 305-0464-780. With an NA of 0.5 the collimating lens will efficiently couple the output from most laser diodes. Also, this lens has a focal length that's slightly shorter than most of the Optima glass lenses - with a 4mm focal length, this lens creates a smaller collimated beam. The minimum working distance is approximately 6 mm from the front surface of the LDM housing. Using a Hitachi HL6312G laser diode as an example, a beam focused at the minimum working distance is approximately 20 x 9.6 microns (1/e2, with 20 microns being the parallel axis); a collimated beam 100 mm from the front surface of the housing is ~0.85 mm x 3.73 mm. When ordering this mounting kit for use with O5.6mm diodes, the part number changes to LDM 3356 KIT. LDM 3400 KIT Interchangeable Apertures to Circularize an Elliptical Beam The LDM 3400 Laser Diode Mount is a unique design with a few features not found in the other Optima laser diode mounts. The 1/2-inch diameter cylindrical housing is essentially split into two sections; the back section holds the laser diode and the collimating lens. The front section holds a changeable aperture and provides the adjustment mechanism for positioning the collimating lens. The front section has a diamond knurl pattern on the outside diameter - to adjust the collimating lens position, just rotate the front section and the collimating lens moves precisely in the z-axis. The laser diode is firmly held in place by a threaded ring that sits on the back surface of the diode - increasing the metal-to-metal contact area and improving heat transfer. Multi-element collimating lens - The lens included with the LDM 3400 mount is the Optima P/N 336-1027-660 or 336-1027-785*. This is possibly one of the best general purpose collimating lens ever designed for visible and near-infrared diodes. When combined with the LDM 3400 mount, the assembly is simple and lens adjustment provides exceptional control. Interchangeable apertures - One technique used to "cleanup" or "circularize" a laser diodes elliptical beam is to pass the collimated beam through a small circular aperture. If the size of the aperture is small enough, the beam exiting the aperture will be circular - an obvious problem with this technique is a loss in optical power. However, most applications don't require a perfectly circular beam - somewhere between the diodes elliptical beam and a circular beam, there's usually an acceptable solution. The LDM 3406 KIT includes 6 circular apertures in the following sizes - 1.14, 1.52, 2.03, 2.54, 3.05, and 4.83mm. The 4.83mm aperture is larger than the clear aperture of the collimating lens, and consequently, has no clipping effect on the beam. The smallest aperture (1.14mm) is approximately equal to the dimension of the collimated beam in the parallel axis (the minor axis of the elliptical beam). When the smallest aperture is imposed on the collimated beam, the output beam will be very close to circular (this depends on the diodes parallel axis divergence angle). The loss in power, as compared with the 4.83mm aperture, is approximately 50%. The larger diameter apertures may be used to cleanup a beam by removing side lobes and other artifacts without causing a significant loss in power. In any case, the range of aperture sizes supplied with the LDM 3406 kit allows the user to evaluate the tradeoffs between beam size and power loss. Ready for Production - The LDM 3400 KIT includes one aperture - once you've determined the optimum size for the aperture, the kit is available in a lower cost production version with only one aperture. Special aperture sizes are available in production quantities; please contact the factory for a quote. When ordering this mounting kit for use with O5.6mm diodes; the part number changes to LDM 3456 KIT or LDM 3457 KIT. The LDM 3456 KIT has one aperture; LDM 3457 KIT includes 6 apertures. * The LDM 3400 Series kits may be special ordered with the 336-1027-140 lens which is AR coated for use with 1300 nm to 1550 nm laser diodes; please contact the factory for pricing and availability.

However, the collimating lens included in the LDM 3500 kit is a very high quality molded glass asphere with a long focal of 8mm, Optima P/N 305-8040-780. This lens creates a very good quality beam in applications where a smaller beam is required at longer distances. It can be used in bar code readers that need a longer depth-of-field and/or work at greater stand-off distances than the typical hand-held device. It's probably most useful in alignment systems and laser levels that project a beam in excess of a hundred feet. The minimum working distance is approximately 90 mm from the front surface of the LDM housing. Using a Hitachi HL6312G laser diode as an example, a beam focused at the minimum working distance is approximately 50 x 23 microns (1/e2, with 50 microns being the parallel axis); a collimated beam 100 mm from the front surface of the housing is ~1.68 mm x 5.30 mm. When ordering this mounting kit for use with O5.6mm diodes, the part number changes to LDM 3556 KIT. LDM 3600 KIT Provides X-Y Alignment for Accurate Beam Pointing The compact cylindrical housing provides the essential heat sink for a O9mm laser diode and a precise three-axis adjustment system for positioning the collimating lens relative to the laser diode. During assembly, the lens is aligned in the x-y axis with the laser diode emission point and adjusted in the z-axis to collimate or focus the beam. The collimating lens included with this kit is a high quality, multi-element lens with a relatively large numerical aperture - Optima P/N 336-1027-660 for visible diodes, or the 336-1027-785 for near-infrared diodes. The minimum working distance is approximately 42 mm from the front surface of the LDM housing. Using a Hitachi HL6312G laser diode as an example, a beam focused at the minimum working distance is approximately 45 x 17 microns (1/e2, with 45 microns being the parallel axis); a collimated beam 100 mm from the front surface of the housing is ~0.98 mm x 4.06 mm. * The LDM 3600 KIT may also be special ordered with the 336-1027-140 lens which is AR coated for use with 1300 nm to 1550 nm laser diodes; please contact the factory for pricing and availability. LDM 3700 KIT and LDM 3800 KIT Easy to Assemble without X-Y Alignment Similar to the LDM 3600 except the lens is adjustable only in the z-axis, controlling the focus or collimation of the beam; there is no provision for moving the lens in the x-y axis. The collimating lens and laser diode are positioned to within 13 microns of the housing mechanical center line; however, due to misplacement of the laser die inside the laser diode package, the optical beam may not be coincident with the housing mechanical axis -- typically, the worse case pointing error is less than 17.5 mrad. The difference between the LDM 3700 KIT and LDM 3800 KIT is as follows: the mechanical details of the lens holder are slightly different and the LDM 3700 housing is 17mm in length, whereas the LDM 3800 housing is 18mm long. The same collimating lens is included with either mounting kit; it's a high quality, multi-element lens with a relatively large numerical aperture - Optima P/N 336-1027-660 for visible diodes, or the 336-1027-785 for near-infrared diodes.* The minimum working distance is approximately 16 mm from the front surface of the LDM housing. Using a Hitachi HL6312G laser diode as an example, a beam focused at the minimum working distance is approximately 27 x 21 microns (1/e2, with 27 microns being the parallel axis); a collimated beam 100 mm from the front surface of the housing is ~0.98 mm x 4.06 mm. When ordering a mounting kit for use with O5.6mm diodes, the part number changes to LDM 3756 KIT or LDM 3856 KIT. Also, please specify which AR coating is required, -660 for visible diodes; or -785 for near-IR diodes.* * The LDM 3700 or 3800 KIT may also be special ordered with the 336-1027-140 lens which is AR coated for use with 1300 nm to 1550 nm laser diodes; please contact the factory for pricing and availability.

This kit provides an excellent compromise between cost and performance -- something in between an assembly using the higher cost multi-element lens and a kit with a lower cost plastic lens. The optical performance of the lens is very good -- it creates a collimated beam which is slightly larger than a beam from the 336-1027 lens, resulting in a beam with less divergence and, consequently, a smaller beam at greater distances. Conversely, due to the longer focal length and larger clear aperture, this lens creates a smaller focused beam. The minimum working distance is approximately 21 mm from the front surface of the LDM housing. Using a Hitachi HL6312G laser diode as an example, a beam focused at the minimum working distance is approximately 24 x 10.5 microns (1/e2, with 24 microns being the parallel axis); a collimated beam 100 mm from the front surface of the housing is ~1.37 mm x 5.12 mm. When ordering this mounting kit for use with O5.6mm diodes, the part number changes to LDM 3956 KIT. LDM 4000 KIT Low Cost Plastic Bi-Aspheric Lens without X-Y Alignment This low cost mounting kit is similar to the LDM 3900 except the collimating lens provided is an molded plastic asphere - Optima P/N 300-0360-780. The minimum working distance is approximately 8 mm from the front surface of the LDM housing. Using a Hitachi HL6312G laser diode, a beam focused at the minimum working distance is approximately 19.5 x 8.6 microns (1/e2, with 19.5 microns being the parallel axis); a collimated beam 100 mm from the front surface of the housing is ~0.92 mm x 3.17 mm. When ordering this mounting kit for use with O5.6mm diodes, the part number changes to LDM 4056 KIT. LDM 4100 KIT Molded Glass Aspheric Lens with provision for X-Y alignment The compact cylindrical housing provides the heat sink for the laser diode and a precise three-axis adjustment system for positioning the collimating lens relative to the laser diode. During assembly, the lens is aligned in the x-y axis with the laser diode emission point and adjusted in the z-axis to collimate or focus the beam. The collimating lens included with this kit is the Optima P/N 310-0065-780, (this lens has the same spec's as the 305-0065-780, except the 310version is in a special mount intended for this diode mounting kit). While the collimating lens is AR coated for 780nm, the lens works very well with both visible and near-infrared diodes. The minimum working distance is approximately 45 mm from the front surface of the LDM housing. Using a Hitachi HL6312G laser diode as an example, a beam focused at the minimum working distance is approximately 45 x 18.5 microns (1/e2, with 45 microns being the parallel axis); a collimated beam 100 mm from the front surface of the housing is ~1.37 mm x 5.12 mm. The LDM 4100 KIT is only available for O9.0mm diodes. (c) Optima Precision Inc. Phone: (800) 544-4118 email: sales@optima-optics.com url: http://www.optima-optics.com REV 01JAN01 Laser Diode Mounting Kits Detailed Description and Specifications: LDM 4200 KIT Bi-aspheric Plastic Lens for Long Distance Applications This laser diode mounting kit is specifically designed to accept the Optima 300-0395-780 plastic aspheric collimating lens. Due to the relatively long focal length of the collimating lens, the housing is longer than most of the Optima laser diode mounts. With a long focal length (16mm) and small numerical aperture (NA=.14) this lens creates a relatively large diameter beam that's more circular than the output from a typical laser diode collimating lens. Also, the 300-0395-780 lens is a very high-quality injection molded plastic lens - this lens has been used in digital laser communication systems which are extremely sensitive to lens aberrations and diffraction patterns that can be misread as data when a beam sweeps across a detector. The only negative aspect of the lens might be the small NA - the coupling efficiency (or total transmission) for most visible laser diodes is just under 50%. Due to the long focal length, the minimum working distance is approximately 153 mm (6 inches) from the front surface of the LDM housing. If the application requires focusing at shorter distances, it would be best to collimate the output from the diode and then use a simple lens like a plano-convex to focus the beam. However, for reference we have measured the beam from the LDM 4200 kit using a Hitachi HL6312G laser diode; a beam focused at the minimum working distance is approximately 51.0 x 36.1 microns (1/e2, with 51.0 microns being the parallel axis); a collimated beam 100 mm from the front surface of the housing is ~3.38 mm x 4.65 mm. When ordering this mounting kit for use with O5.6mm diodes, the part number changes to LDM 4256 KIT. LDM 4500 KIT Low Cost Plastic Bi-Aspheric Lens, Small Collimated Beam Similar to the LDM 4000 except the collimating lens provided is a molded plastic asphere, P/N 300-0380-780. With a short focal length of 3.4mm, this lens provides at relatively small collimated beam. A large numerical aperture (NA) of 0.47 provides excellent coupling efficiency with most laser diodes. The minimum working distance is approximately 4 mm from the front surface of the LDM housing. Using a Hitachi HL6312G laser diode as an example, a beam focused at the minimum working distance is approximately 26.5 x 7.3 microns (1/e2, with 26.5 microns being the parallel axis); a collimated beam 100 mm from the front surface of the housing is ~0.74 mm x 2.89 mm. When ordering this mounting kit for use with O5.6mm diodes, the part number changes to LDM 4556 KIT. LDM 5000 KIT Low Wavefront Aberration, Larger Collimated Beam Unique housing design - This housing has a flat mounting surface perpendicular to the optical axis, ideal for attachment to a printed circuit board or thermal electric cooler. Four #2-56 threaded holes in the base facilitate mounting, alignment, and aiming - if the base is attached to a "soft" mount like a rubber o-ring or wave washer, the beam can be "pointed" by selectively adjusting the four mounting screws attached to the base. X-Y alignment - The laser emission point may be aligned with the lens optical axis by translating the diode in the x-y axis. While the lens is free to move in the z axis (controlling focus or collimation) the lens does not rotate, minimizing lateral shift in the focused beam during the lens adjustment process. The collimating lens provided is a very high quality, diffraction-limited, multi-element lens with a large clear aperture and medium NA, Optima P/N 336-0965-780. With the larger clear aperture and excellent wavefront quality, this lens is intended for more demanding applications; such as laser diode instrumentation and/or long distance measurement applications. Broad range of lens adjustment - The minimum working distance is approximately 12 mm from the front surface of the LDM housing. Using a Hitachi HL6312G laser diode as an example, a beam focused at the minimum working distance is approximately 30 x 15.5 microns (1/e2, with 30 microns being the parallel axis); a collimated beam 100 mm from the front surface of the housing is ~1.52 mm x 5.71 mm. The LDM 5000 KIT is available in limited quantities and only for O9.0mm diodes. 26.9mm O25.4mm LDM 5000 KIT (c) Optima Precision Inc.

Last modified: March 13, 2001 2-Axis and 4-Axis Precision Positioners - Optima Precision Inc. 2-Axis and 4-Axis Precision Positioners Precision XY Translator & XY Translator plus Tilt Control (shown above) These unique XY Translators help reduce the tedious process of accurately positioning optics and optoelectronic components. Compared with a conventional translation stage, these units offer several advantages. In a very compact and economical package, the XY Translators provide smooth, precision movement in two axes. Ideally suited for OEM or prototype use in optical instruments, the XY Translators facilitate the accurate positioning of light sources, optics, fibers, and detectors or sensors for maximum performance. While the positioners were designed for an optical instrument, we've found them indispensable in our optical bench set-ups where small optics and other critical devices must be carefully aligned. The small footprint of the XY Translators and their compatibility with standard optical bench post holders, allows the use of multiple units in the space typically required by one translation stage. Precise x-y motion is controlled by moving a pair of levers on the side of the unit. One lever moves the optical component in the X direction while the second lever controls the Y axis movement. A positive locking mechanism ensures the mount will be permanently locked in place once the desired position is established. Components are retained in the mount with a nylon-tipped set screw which gently, but positively, holds the component against two contact points, ensuring a stable three-point mounting system. Part number 250-0015 will accept components up to 15mm in diameter, while P/N 250-0025 accepts components up to 25.4mm in diameter. Additional hardware may be attached to the front surface of the mount by using the four #4-40 threaded holes. Two #8-32 threaded holes on the bottom edge of the mount are compatible with most standard optical bench posts. 2-Axis and 4-Axis Precision Positioners - Optima Precision Inc. XY Translator plus Tilt Adjustment Precision control of angular adjustment is available in the four axis positioners. With the same basic operation as the XY Translators described above, the four axis unit provides the added capability of tilt control. Kinematic angular adjustment is achieved by using a pair of 1/4-80 adjustment screws while a pair of levers independently control the x-y movement. The kinematic adjustment screws may be ordered with either screwdriver adjustment slots or with rubber covered knobs for convenient tool-free adjustment.

Laser Diode Optics Cost Effective Optima Lenses for Collimating and Focusing Laser Diodes Collimating and focusing a laser diode is perhaps the most critical prerequisite in any laser diode application. While the characteristics of a laser diode might be ideal for your application, the laser diode must be matched with the appropriate optics to create a useable beam. Typically, the laser diode is collimated with one lens and a second lens is used to focus the beam. However, many applications exist where a single lens is used to either focus or collimate the beam. In either case, most laser diodes require a collimating lens with a large numerical aperture (NA) to efficiently capture the widely divergent perpendicular axis.

For the most demanding application, a three or four element spherical lens achieves a level of optical performance difficult to obtain with any single element lens. To assure diffraction-limited performance, start by collimating the diode with one of the Optima 336 Series multi-element lenses. All 336 Series lenses are computer optimized to minimize aberrations, maximize coupling efficiency, and function over a broad range of wavelengths and normal manufacturing tolerances. The lenses can be used with most visible and near-infrared laser diodes and are currently used in a wide array of products including the following: Bar-code Readers Alignment and Distance Measuring Systems Positioning and Edge Finding Equipment Light Scatter and Particle Counters Diode Based Interferometers Fiber Optic Communications The following paragraphs briefly describe the attributes and differences between the three 336 Series collimating lenses. The 336-1027 is an excellent general purpose collimating lens, its small physical size is compatible with both 5.6mm and 9.0mm diameter laser diodes, making a very compact assembly. A relatively large numerical aperture (NA) of 0.48 captures a large percentage of the beam from most common laser diodes -- coupling efficiencies typically range from 91% to 95%. The 336-1027 is available with three standard MgF2 anti-reflection coatings designated as: -660 for visible laser diodes (633nm to 750nm); -785 for use with most near-infrared diodes (750nm to 980nm); and the -140 AR coating for use with 1300nm and 1550nm laser diodes. The 336-0965-780 is a very high quality collimating lens suitable for more demanding applications. With a longer focal length and larger clear aperture, this lens provides a slightly larger collimated beam and consequently lower beam divergence. A moderate numerical aperture of 0.389 provides coupling efficiencies ranging from 83% to 85%. The 336-0808-830 has a longer focal length and larger clear aperture than either of the lenses described above creating the largest collimated beam diameter. The 336-0808-830 is recommended for precision alignment systems, laser range finding, and other applications that require a laser diode beam to be projected over long distances. Multiple Element Focusing Lens: The 336-0000-780 lens is a three element spherical lens used to refocus the collimated beam from a laser diode. For optimum performance, the focusing lens should be used with a collimating lens having the same size clear aperture, i.e. the 336-1027 collimating lens. In this case, the large numerical aperture and short focal length of the focusing lens will provide superior coupling efficiency and diffraction-limited spot.

Collimating and Focusing Lenses for Laser Diodes Diffraction-limited and very cost effective, a precision-molded glass aspheric lens is an attractive compromise between a multi-element lens and a molded plastic lens. The molded glass asphere has two basic advantages over a multi-element lens; first, the aspheric design reduces spherical aberration and coma in a single element; and second, overall light transmission is generally greater with fewer optical surfaces. As compared with plastic lenses; molded glass aspheric lenses will operate over a much broader temperature and humidity range without performance degrading. Because of these advantages, molded glass lenses are often used in products such as laser printers, optical disc storage devices, and optical communications systems. New Lens -- A larger numerical aperture is often very desirable when coupling a collimating lens with a laser diode. Our newest molded glass asphere P/N 305-0464-780, has an NA of 0.5 and a focal length of 4mm which seems ideally suited for many laser diode applications. With a 0.5 NA a coupling efficiency over 90% can be achieved with most diodes. Detailed specifications are listed below: The popular 305-0065-780 aspheric lens is available in three configurations: an unmounted single element, part number 305-0065-780, and two convenient mounted lenses which help reduce some of the tedious problems associated with handling a very small lens. The 306-0065-780 mount has an extra-fine pitch thread (.375-64) on the outside diameter that facilitates precise control in adjusting the focus or collimation of a laser diode. The 310-0065-780 mount is a plain 8mm diameter aluminum cell that can be easily incorporated into the user's laser diode assembly.

Collimating and Focusing Lenses for Laser Diodes While glass lenses are preferred, there are several product applications where a high quality plastic lens can be effectively utilized. The 300 Series plastic aspheric collimating and objective lenses offer a lower cost alternative to glass and still perform well over a temperature range actually exceeding the upper limit for most laser diodes. Plastic lenses are used in products such as laser pointers, construction levels, and less critical alignment and position sensing devices. If you need a collimated beam with smaller dimensions, consider using the 300-0380-780 lens or, the LDM 4500 KIT. For example... when used with the Hitachi HL6312G (635nm/5mW) laser diode, a collimated beam measures approximately 0.715 mm in the parallel axis by 2.85 mm in the perpendicular axis, with divergence angles of 1.2 mrad x 0.34 mrad respectively. (The figures mentioned may vary from one diode to another or, with other manufacturers diodes).

New Lens, P/N 300-0380-780 Creates a Smaller Collimated Beam -- If you need a collimated beam with smaller dimensions, consider using the 300-0380-780 plastic lens and/or the Optima LDM 4500 KIT Laser Diode Mounting Kit which includes the new smaller plastic asphere. As and example... when this lens is used with the Hitachi HL6312G (635nm/5mW) laser diode, a collimated beam measures approximately 0.715 mm in the parallel axis by 2.85 mm in the perpendicular axis, with divergence angles of 1.2 mrad x 0.34 mrad respectively. (The figures mentioned may vary from one diode to another or, with other manufacturers diodes). P/N 300-0395-780 Creates a Larger, More Circular Collimated Beam -- If you need a collimated beam with low divergence and consequently a smaller beam at long distances, consider the Optima 300-0395-780. With a long focal length (16mm) and small numerical aperture (NA=.14) this lens creates a relatively large diameter beam that's more circular than the output from the typical laser diode collimating lens. Also, the 300-0395-780 lens is a very high-quality injection molded plastic lens this lens has been used in digital laser communication systems which are extremely sensitive to lens aberrations and diffraction patterns that can be misread as data when a beam sweeps across a detector. The only negative aspect of the lens might be the small NA the coupling efficiency (or total transmission) for most visible laser diodes is just under 50%. Please refer to the lens specifications below for detailed information. For reference we've profiled the beam from a 300-0395-780 lens using a Hitachi HL6312G laser diode; at 100 mm from the lens, a collimated beam measures ~3.38 mm x 4.65 mm (measured at the 1/e2 clip point, with 3.38mm being the laser diode's parallel axis).

Last modified: December 30, 2000 fi Optima Laser Diode Optics Cost Effective Lenses for Collimating and Focusing Laser Diodes Collimating and focusing a laser diode is perhaps the most critical prerequisite in any laser diode application. While the characteristics of a laser diode might be ideal for your application, the laser diode must be matched with the appropriate optics to create a useable beam. Typically, the laser diode is collimated with one lens and a second lens is used to focus the beam. However, many applications exist where a single lens is used to either focus or collimate the beam. In either case, most laser diodes require a collimating lens with a large numerical aperture (NA) to efficiently capture the widely divergent perpendicular axis. Multi-Element Lenses for Optimal Performance For the most demanding applications, a three or four element spherical lens achieves a level of optical performance difficult to obtain with any single element lens. To assure diffraction-limited performance, start by collimating the diode with one of the Optima 336 Series multi-element lenses. All 336 Series lenses are computer optimized to minimize aberrations, maximize coupling efficiency, and function over a broad range of wavelengths and normal manufacturing tolerances. The lenses can be used with most visible and near-infrared laser diodes and are currently used in a wide array of products including the following: * Alignment and Distance Measuring Systems * Linear and Rotary Encoders * Positioning and Edge Finding Equipment * Free-space Laser Communication Systems * Light Scatter and Particle Counters * Bar-code Readers The following paragraphs briefly describe the attributes and differences between the three 336 Series collimating lenses. 336-1027-660, -785, and -140 -- These are excellent general purpose collimating lenses; its small physical size is compatible with both 5.6mm and 9.0mm diameter laser diodes, making a very compact assembly. A relatively large numerical aperture (NA) of 0.48 captures a large percentage of the beam from most common laser diodes -- coupling efficiencies typically range from 91% to 95%. The 336-1027 is available with three standard MgF2 anti-reflection coatings designated as: -660 for visible laser diodes (633nm to 750nm); -785 for use with most near-infrared diodes (750nm to 980nm); and the -140 AR coating for use with 1300nm to 1550nm laser diodes. 336-0965-780 -- This is a very high quality collimating lens suitable for more demanding applications where wavefront aberration is critical. With a longer focal length and larger clear aperture, this lens provides a slightly larger collimated beam and consequently lower beam divergence. A moderate numerical aperture of 0.389 provides coupling efficiencies ranging from 83% to 85%. 336-0808-830 -- With a longer focal length and larger clear aperture than either of the lenses described above, this lens creates the largest collimated beam diameter. The 336-0808-830 is recommended for precision alignment systems, laser range finding, and other applications that require a laser diode beam to be projected over long distances with low divergence. Multiple Element Focusing Lens -- The 336-0000-780 lens is a three element spherical lens used to refocus the collimated beam from a laser diode. For optimum performance, the focusing lens should be used with a collimating lens having the same size clear aperture, i.e. the 336-1027 collimating lens. In this case, the large numerical aperture and short focal length of the focusing lens will provide superior coupling efficiency and diffraction-limited spot.

The molded glass asphere has two basic advantages over a multi-element lens; first, the aspheric design reduces spherical aberration and coma in a single element; and second, overall light transmission is generally greater with fewer optical surfaces. As compared with plastic lenses; molded glass aspheric lenses will operate over a much broader temperature and humidity range without performance degrading. Because of these advantages, molded glass lenses are often used in products such as laser printers, optical disc storage devices, and optical communications systems. New Lens P/N 305-0464-780 -- A larger numerical aperture is often very desirable when coupling a collimating lens with a laser diode. Our newest molded glass asphere P/N 305-0464-780, has an NA of 0.5 and a focal length of 4mm which is ideally suited for many laser diode applications.

Mounted aspheric lens with fine pitch threads -- The popular 305-0065-780 aspheric lens is available in three configurations: an unmounted single element, part number 305-0065-780, and two convenient mounted lenses which help reduce some of the tedious problems associated with handling a very small lens. The 310-0065-780 mount is a plain 8mm diameter aluminum cell that can be easily incorporated into the user's laser diode assembly. Lenses p/n 305-0464-780, 305-4606-670, and p/n 305-8040-780 are also available in a threaded mount, the p/n prefix changes to 306-xxxx-xxx or 307-xxxx-xxx as listed in the table below. All of the threaded mounts have an extra-fine pitch thread (.375-64) on the outside diameter that facilitates precise control in adjusting the focus or collimation of a laser diode.

The 300 Series plastic aspheric collimating and objective lenses offer a lower cost alternative to glass and still perform well over a temperature range actually exceeding the upper limit for most laser diodes. Plastic lenses are used in products such as laser pointers, construction levels, and less critical alignment and position sensing devices. New Lens, P/N 300-0380-780 Creates a Smaller Collimated Beam -- If you need a collimated beam with smaller dimensions, consider using the 300-0380-780 plastic lens and/or the Optima LDM 4500 KIT Laser Diode Mounting Kit which includes the new smaller plastic asphere. As and example... when this lens is used with the Hitachi HL6312G (635nm/5mW) laser diode, a collimated beam measures approximately 0.715 mm in the parallel axis by 2.85 mm in the perpendicular axis, with divergence angles of 1.2 mrad x 0.34 mrad respectively. (The figures mentioned may vary from one diode to another or, with other manufacturers diodes). P/N 300-0395-780 Creates a Larger, More Circular Collimated Beam -- If you need a collimated beam with low divergence and consequently a smaller beam at long distances, consider the Optima 300-0395-780. With a long focal length (16mm) and small numerical aperture (NA=.14) this lens creates a relatively large diameter beam that's more circular than the output from the typical laser diode collimating lens. Also, the 300-0395-780 lens is a very high-quality injection molded plastic lens this lens has been used in digital laser communication systems which are extremely sensitive to lens aberrations and diffraction patterns that can be misread as data when a beam sweeps across a detector. The only negative aspect of the lens might be the small NA the coupling efficiency (or total transmission) for most visible laser diodes is just under 50%. Please refer to the lens specifications below for detailed information. For reference we've profiled the beam from a 300-0395-780 lens using a Hitachi HL6312G laser diode; at 100 mm from the lens, a collimated beam measures ~3.38 mm x 4.65 mm (measured at the 1/e2 clip point, with 3.38mm being the laser diode's parallel axis).

DLM 3300 / 3500 / 3600 Visible and Near-infrared with wavelengths from 635nm to 785nm and Optical Power ranging from 1mW to 35mW Optima's Diode Laser Modules (DLM) combine the three essential components for any diode laser system: the laser diode, drive circuit, and collimating lens into a compact cylindrical package. Applications for Diode Laser Modules continue to expand into new areas including the following fields and products: Industrial - Alignment, Positioning Systems, Edge Detection, and Distance Measuring Scientific - Particle Counters, Light Scatter, Chemical Analysis and Fluorescence, Atomic Physics Medical - Cell Counting, Blood Analysis, and Patient Positioning in Medical Imaging Systems Graphic Arts - Laser Printers and Typesetting Equipment Laser Diode Modules, Visible & Near-Infrared, 635nm to 780nm - Optima Communication - Free Space Laser Communications These applications, and many others, require high-quality components and workmanship. At Optima, we've designed and built-in that quality -- we utilize our proprietary collimating optics and laser drive circuit. Attention to detail throughout manufacturing and assembly includes a 100% burn-in, environmental test sequence, and documentation. The final result creates a reliable diode laser module for the industrial, medical, and scientific community. The module housing is precision machined from high strength 6061T-6 aluminum, providing a substantial heatsink for the laser diode, helping extend diode lifetime. The diode drive circuit operates the laser in the Continuous-wave (CW) and Automatic Power Control (APC) mode. Also referred to as the "photodiode feedback" mode, this closed-loop monitoring circuit uses the laser diodes internal photodiode as an optical power sensor. Current from the photodiode is fed back to the APC circuit, thereby regulating the drive current supplied to the laser diode. This circuit is generally recommended for stable optical power output in an environment where the ambient temperature will fluctuate. The laser drive circuit also includes ESD protection and reverse polarity protection; a slow-start circuit and filtering ensure power surges do not affect the laser diode. A green LED on the back of the module indicates when the laser diode is operating. (CDRH Class IIIb modules incorporate a three second turn-on delay). Three basic modules are available -- The DLM 3300 Series uses the Optima glass asphere P/N 305-0464-780 which provides a slightly smaller collimated beam than the two other modules. The DLM 3500 Series use an Optima glass aspheric collimating lens P/N 305-0065-780, while the DLM 3600 uses Optima's diffraction-limited, four-element glass collimating len P/N 336-1027-660 lens for visible diodes, or the P/N 336-1027-785 lens for use with near-infrared diodes. All modules are supplied with a collimated beam; however, the lens is user-adjustable allowing the module to be focused at a specific distance. The approximate minimum focus distance for each module is listed in the specifications table below. For complete specifications on the collimating lenses, please refer to the Laser Diode Optics page. The diode laser modules may be configured with a variety of laser diodes offering flexibility in design; optimizing the operating wavelength and output power for your specific application. Visible diode wavelengths range from 635nm to 690nm with laser diode power output ranging from 1mW to 35mW. A complete range of diode laser modules is listed below and in the Optima price list, along with the mechanical dimensions, diode specifications and the applicable CDRH classifications.

Using an input voltage greater than 5 volts results in excess heat which must be dissipated by the module. For best results when operating at increased input voltage or at elevated ambient temperatures, the module should be mounted using a metal mounting bracket or clamp to increase the thermal mass and facilitate heat transfer. In any case, the module should not be mounted in a plastic structure which inhibits heat transfer. Note 2) Diode dependent specification. Note 3) The DLM 3300 series require a +5VDC power supply that is filtered and well regulated (+0.5 / -0.25 volts). Note 4) Distance measured from the front surface of the module to the focused spot.

General Description Cost effective, high quality, miniature diode laser module for OEM products Two highly visible wavelengths available - choose either 635nm or 650nm DLM 2100 Series uses an Optima molded plastic collimating lens for lower cost DLM 2300 Series uses an Optima molded glass asphere for better optical performance Adjustable lens for focusing or collimating the beam Adjustable optical power control - up to 3mW maximum output These cost effective diode laser modules are specifically designed for high-volume OEM applications and are not intended to be used as a stand alone component. As shown in the above picture, the size of the diode housing is very small and the drive circuit is exposed for access to the power control. Therefore, these modules should be Laser Diode Modules, Visible, 635nm and 650nm - Optima incorporated into another product's housing or structure; one that will provide additional heat sinking for the laser diode and protection for the drive circuit. These modules should not be confused with low-priced units imported from the Far East. While the cost is competitive, Optima's DLM 2100 and DLM2300 Series modules use only first quality components - and that's not just marketing hype. There are basically three essential components in a laser diode module: First, the laser diode - we use only first quality 635nm and 650nm laser diodes from the major Japanese manufacturers like Hitachi and Toshiba. Other module manufacturers may use second or third grade diodes - in some cases the diodes fail the diode manufacturers first grade tests and are rejected without further testing - those diodes can wind-up in some module as untested, or perhaps used in modules with their photodiode lead clipped off. Second, the optics - the Optima DLM 2100 Series is our lower cost module and it uses a molded plastic aspheric lens that will actually meet (or exceed) it's listed specifications over an operating temperature range that exceeds the operating temperature of the laser diode. Why is this important? If the collimating lens temperature range doesn't match or exceed the laser diodes temperature range, it's very likely the lens will be unstable. Subtle changes in the lens thickness or surface shape will cause the beam to change size and shape (usually it gets larger). It can also affect the beam's pointing stability, causing the beam to wander as the laser diode, module housing, and lens temperature increase. For better optical performance, the Optima DLM 2300 Series module uses our high quality molded glass asphere. The glass lens is less sensitive to temperature fluctuations than a plastic lens and generally better suited for applications with a harsh environment. Also, visible birefringence and diffraction patterns are significantly reduced with a molded glass asphere. Third, the drive circuit - we utilize only the best quality electrical components and SMT technology to produce a reliable and thoroughly tested circuit board assembly. The specifications for the DLM 2100 Series and the DLM 2300 Series are basically the same and are listed in the table below. Both modules are shipped from the factory with the beam collimated and the optical power set to <1mW. The lens position can be adjusted by the user to provide a focused beam, a collimated beam, or a slightly divergent beam. The optical power may be adjusted by changing the potentiometer setting - to maximize the diodes lifetime, it's strongly recommended that a 3mW maximum optical power limit is not exceeded, (see note 1 below).

Each module is tested at the factory, the beam is collimated and the optical output set between 0.95mW and 1mW with an input voltage of +3.0 volts. The optical power may be adjusted by the user; however, a maximum optical output of 3mW must not be exceeded - an optical power meter is required to accurately set the optical output. Exceeding the 3mW limit will severely shorten the diodes lifetime and/or may cause immediate failure. Refer to the application notes and glossary section if you need clarification on laser lifetime, power settings, failure modes, etc. Note 2) The optimum input voltage is +3.0 volts; however, the modules will operate over a range from +3.0 to 5.0 volts. The Using an input voltage greater than 3 volts results in excess heat which must be dissipated by the module. For best results when operating at increased input voltage or at elevated ambient temperatures, the module should be mounted using a metal mounting bracket or clamp to increase the thermal mass and facilitate heat transfer. In any case, the module should not be mounted in a plastic structure which inhibits heat transfer. Note 3) The optical output power is directly related to the input voltage. If the input power is increased, the optical output will increase. Therefore using an optical power meter, the optical power must be set with the module operating at the highest anticipated input voltage. For operation at a constant output level, the supply voltage should be regulated. If desired, the optical output may be controlled externally by varying the input or supply voltage. Laser Diode Modules, Visible, 635nm and 650nm - Optima Note 4) Diode dependent specification -- values will vary from one diode module to another. Note 5) The collimated beam is measured at the 1/e2 point. The first number (smaller value) is the laser diodes parallel axis while the second number is the perpendicular axis. The values listed are typical and may vary from diode to diode. Note 6) The focused beam is measured at the 1/e2 point. This measurement is taken at the minimum focus distance as listed in the table above -- the distance is measured from the front of the module housing to the focused spot.

The lens position can be adjusted by the user to provide a focused beam, a collimated beam, or a slightly divergent beam. The optical power may be adjusted by changing the potentiometer setting - to maximize the diodes lifetime, it's strongly recommended that a 3mW maximum optical power limit is not exceeded, (see note 1 below).

Applications for Diode Laser Modules continue to expand into new areas including the following fields and products: * Industrial - Alignment, Positioning Systems, Edge Detection, and Distance Measuring * Scientific - Particle Counters, Light Scatter, Chemical Analysis and Fluorescence, Atomic Physics * Medical - Cell Counting, Blood Analysis, and Patient Positioning in Medical Imaging Systems * Graphic Arts - Laser Printers and Typesetting Equipment These applications, and many others, require high-quality components and workmanship. At Optima, we've designed and built-in that quality -- we utilize our proprietary collimating optics and laser drive circuit. Attention to detail throughout manufacturing and assembly includes a 100% burn-in, environmental test sequence, and documentation. The final result creates a reliable diode laser module for the industrial, medical, and scientific community. The module housing is precision machined from high strength 6061T-6 aluminum, providing a substantial heatsink for the laser diode, helping extend diode lifetime. The diode drive circuit operates the laser in the Continuous-wave (CW) and Automatic Power Control (APC) mode. Also referred to as the photodiode feedback mode, this closed-loop monitoring circuit uses the laser diodes internal photodiode as an optical power sensor. Current from the photodiode is fed back to the APC circuit, thereby regulating the drive current supplied to the laser diode. This circuit is generally recommended for stable optical power output in an environment where the ambient temperature will fluctuate. The laser drive circuit also includes ESD protection and reverse polarity protection; a slow-start circuit and filtering ensure power surges do not affect the laser diode. A green LED on the back of the module indicates when the laser diode is operating. (CDRH Class IIIb modules incorporate a three second turn-on delay). Three basic modules are available -- The DLM 3300 Series uses the Optima glass asphere P/N 305-0464-780 which provides a slightly smaller beam than the two other modules. The DLM 3500 Series use an Optima glass aspheric collimating lens P/N 305-0065-780, while the DLM 3600 uses Optima's diffraction-limited, four-element glass collimating len P/N 336-1027-660 lens for visible diodes, or the P/N 336-1027-785 lens for use with near-infrared diodes. All modules are supplied with a collimated beam; however, the lens is user-adjustable having a minimum focus distance of about 24mm from the front surface of the DLM housing. For complete specifications on the collimating lenses, please refer to the Laser Diode Optics page at the Optima website -- URL http://www.optima-optics.com The diode laser modules may be configured with a variety of laser diodes offering flexibility in design; optimizing the operating wavelength and output power for your specific application. Visible diode wavelengths range from 635nm to 685nm with laser diode power output ranging from 1mW to 35mW. A complete range of diode laser modules is listed on the following page and in the Optima price list, along with the mechanical dimensions, diode specifications and the applicable CDRH classifications.

A Collimated Diode Laser (CDL) is a compact cylindrical assembly often referred to as a light pen. Each CDL includes; a laser diode and collimating lens which are assembled into a precisely machined, black anodized, aluminum housing; the laser diode drive circuit is not included. CDL's are often a viable solution in the following situations: Optical assembly techniques and specialized optical test instruments are not available Laser drive circuit is incorporated with other electronics in the product or application Special laser drive requirements; i.e. pulse drive or modulation Optima offers a comprehensive selection of CDL assemblies based on the seven laser diode mounting systems described on the Laser Diode Mounting Kit page. Combining these proprietary mounting systems with the myriad of laser diodes available today allows us to efficiently assemble a CDL specifically tailored to your requirements. In critical applications, a CDL with an x-y lens alignment system is generally preferred. During the assembly process, the optical axis of the collimating lens is precisely aligned with the laser diode's emission point, ensuring a symmetric beam with better static alignment. The collimating lens is then adjusted in the z-axis to focus or collimate the beam. Test data is provided with all CDL's listing specific characteristics of the laser diode, drive current required at various power levels, and the beam divergence specifications. A partial listing of the CDL units available is included in the current Optima price list. Many laser diodes are available from our stock and inquiries with special requirements such as custom mounts or special optical requirements are welcome.

PD200.PDF (71K) Click on the file name to download an Adobe PDF file covering this section. At Optima we're often asked to recommend an optical power meter for general purpose use... Whether it's for use in the R&D lab, a production environment, or for servicing laser products in the field, the Ophir model PD200 is a cost effective solution for measuring one or two specific laser wavelengths. What makes PD200 unique is it's straightforward simplicity - with only three basic controls, there's no elaborate set-up or calibration procedure required - just turn on the power, select the correct wavelength and power range, and you're ready to make measurements up to 200mW. Laser Power Meter - Ophir PD200 Power Meter The large 3-1/2 digit LCD display has exceptionally good contrast and can be back-lit for improved viewing in low light situations. The PD200 is completely portable - the display unit has a built-in rechargeable battery that lasts approximately 30 hours between charging cycles, and the system includes a 12 volt wall-mounted power supply/charger. The PD200 utilizes a calibrated, large area silicon photodiode for measuring optical power. The photodiode's calibration data is stored in the photodiode assembly and each PD200 sensor is calibrated for two specific wavelengths. The user may select either wavelength (WL1 or WL2) with a rocker switch on the front panel. The factory calibrated wavelengths available are listed in the specifications table below. Also, a photodiode response curve is supplied with each meter, which will allow the user to extrapolate to other nearby wavelengths. The display housing is injection molded plastic while the photodiode sensor is mounted in a machined aluminum housing with a convenient swivel head. We've found the swivel head has two subtle benefits; in confined spaces it often helps to accurately position the detector. Likewise, when the sensor head is used with standard optical bench holders, the swivel head makes it easy to tilt the head slightly - reducing unwanted back reflections into the laser source. An optional stand (as shown in the picture above) is also available for the detector. Application note: Are you considering one of the new hand-held power meter probes? A self-contained probe may be cheaper and appear to offer convenience; however, please consider this... We've found in most applications we keep the sensor head mounted on an optical bench post and/or stand. The sensor head can easily be placed in the beam that's being measured and your hands are free for making adjustments to the optics or electronics. Unless you have a few extra hands, it's very difficult to keep a sensor accurately positioned in the beam while making adjustments and reading a display.

Anamorphic Prisms PRISM.PDF (67K) Click on the file name to download an Adobe PDF file covering this section. Beam Shaping and Circularization for Laser Diodes Anamorphic prisms are used to change the dimension of a beam in one axis, the effect being analogous to that of a cylindrical lens. Depending on the orientation of the prisms, the beam size may be either reduced or expanded and the amount of change is variable depending on the angular position of the prisms. The output from most laser diodes is elliptical in cross-section, even after collimation. Depending on the type of laser diode, the aspect ratio of the elliptical beam might be as small as 2:1 or as large as 5:1. In many applications the elliptical beam shape might be useable or even desirable; however, other applications may require beam shaping or circularization. If beam shaping is required, a system using a pair of anamorphic prisms has three significant benefits. One, a pair of prisms can be designed into a much more compact package than a telescope using cylindrical optics. Secondly, the ability of adjusting the position of the prisms allows the user to compensate for variations from one diode to another. And third, the prisms are more cost effective than cylindrical lenses of comparable quality. To modify the beam from a laser diode, the anamorphic prisms are inserted into the beam path after the laser diode is collimated. Magnification is controlled by the angular position of the prisms with respect to the incoming beam and like a telescope, the prism system can be reversed to reduce the beam rather than expand the beam. The prisms are unmounted, allowing the user to position each prism independently as required.

Case Temperature (Tc) - Device temperature measured at the base of the package. Operating Temperature (Topr) - Range of case temperatures within which the device may be safely operated. Optical Power Output (Po) - Maximum allowable instantaneous optical power output in either continuous (CW) or pulse operation. Up to this point, there are no kinks in the optical power output vs. forward current curve. Important note: The optical power output specification is applicable to the bare laser diode - it does not allow for, or take into consideration, any optics that may be in the optical path, such as a collimating lens located between the laser diode and a power meter or other detector. Caution: Do not exceed the specified optical power output -- even an instantaneous (less than a nanosecond) application of excessive current or voltage may cause deterioration or catastrophic optical damage (COD) to the facets. Reverse Voltage (VR) - Maximum allowable voltage when reverse bias is applied to the laser diode or photodiode. For laser diodes with an internal monitor photodiode, the reverse voltage is specified for the laser diode as VR (LD) and for the photodiode as VR (PD). Storage Temperature (Tstg) - Range of case temperatures within which the device may be safely stored. Terms Describing Laser Diode Electro-optical Characteristics: Commonly used abbreviations are shown in parentheses. Automatic Power Control (APC) - Laser diode drive circuit based on a photodiode feedback loop that monitors the optical output and provides a control signal for the laser diode which maintains the operation at a constant optical output level. See additional information below on Drive Circuits and Operating in Constant Power Mode vs. Constant Current Mode. Automatic Current Control (ACC) or Constant Current - Laser diode drive circuit that operates the laser diode without a photodiode feedback loop, the laser diode is simply driven at constant current. The optical output will fluctuate as the laser diode temperature changes. See additional information below on Drive Circuits and Operating in Constant Power Mode vs. Constant Current Mode. Fall Time - Time required for the optical output to fall from 90% to 10% of its maximum value. Mode Hopping - As the temperature of the laser chip increases, the operating wavelength also increases. Rather than a smooth, continuous transition in the operating wavelength, the wavelength makes discrete jumps to the longer wavelength modes. The phenomenon is referred to as "mode hopping" or "mode jumps". Monitor Current (Im) - The current through the photodiode, at a specified reverse bias voltage, when the laser diode is producing its typical optical power output. Note: The manufacturers data may list specifications based on operation at lower optical output power than the devices absolute maximum rating. For example, the test condition might be 20mW for a diode with an absolute maximum optical output of 30mW. Operating Current (Iop) - The amount of forward current through the laser diode necessary to produce the specified typical optical output at a specified operating temperature. Operating Voltage (Vop) - The forward voltage across the laser diode when the device produces its specified typical optical output at a specified operating temperature. Photodiode Dark Current (ID(PD)) - The current through the reverse biased internal monitor photodiode when the laser diode is not emitting. Revised 02DEC98 (c) Optima Precision Inc. Phone: (503) 638-2525 email: sales@optima-optics.com url: http://www.optima-optics.com Optima(R) Laser Diode Application Notes and Glossary Positional Accuracy (Dx, Dy, Dz) - Also referred to as emission point accuracy. These specifications define the positional accuracy of the laser diode emitter with respect to the device package. Delta x and delta y are measured as the planer displacement of the chip from the physical axis of the package. Delta z is measured perpendicular to the reference surface. Specifications may list both angular error expressed in degrees and the linear error in microns. Rise Time - Time required for the optical output to rise from 10% to 90% of its maximum value. Slope Efficiency (SE) or (S) - Also referred to as differential efficiency. This is the mean value of the incremental change in optical power for an incremental change in forward current when the device is operating in the lasing region of the optical power output vs. forward current curve. Threshold Current (Ith) - The boundary between spontaneous emission and the stimulated emission shown on the optical power output vs. forward current curve. Below the threshold current point, the output resembles the incoherent output from a LED; at or above the specified threshold current, the device begins to produce laser output. Once past the threshold point, stimulated emission is achieved and the optical output increases significantly for a small increase in forward current. Wavelength (lp) - The wavelength of light emitted by the laser diode. For a single mode device, this is the wavelength of the single spectral line of the laser output. For a multi-mode device, this is the wavelength of the spectral line with the greatest intensity. Terms Describing Laser Diode Optical Characteristics: Commonly used abbreviations are shown in parentheses. Aspect Ratio (AR) - The ratio of the laser diode's divergence angles, (perpendicular) and // (parallel). A diode with a 27 perpendicular divergence and a 9 parallel divergence has an elliptical beam with an aspect ratio of 3:1. Astigmatism (As) or (DAs) - The laser beam appears to have different source points for the directions perpendicular and parallel to the junction plane. The astigmatic distance is defined as the distance between the two apparent sources. A laser diode with a large amount of astigmatism must have the astigmatism corrected (or reduced) if the laser diode output is to be accurately focused - otherwise, the resulting focused beam will be astigmatic. Beam Divergence () and (//) - Also referred to as radiation angles. The beam divergence is measured as the full angle and at the half-maximum intensity point, known as Full Width Half Maximum or FWHM. Angular specifications are provided for both the perpendicular axis and parallel axis. Coupling Efficiency - The beam from the laser diode diverges as defined by the beam divergence specification. In coupling the laser diodes widely divergent beam into a lens or other device such as a fiber, the result is typically less than 100%. Coupling efficiency is defined as the percentage of total power output from the laser which effectively enters the external device (i.e. a lens or fiber). Far Field Pattern (FFP) - Intensity profile of the beam when measured at a distance from the front facet of the laser diode chip. Multimode Diodes - Laser diodes have either single or multiple longitudinal modes. For a multimode laser diode the emission spectrum consists of several individual spectral lines with a dominant line (line with the greatest intensity) occurring at the nominal wavelength of the device. Multimode laser diodes are often desirable as problems with mode hops are suppressed - consequently, multimode diodes generally have a better signal-to-noise ratio. Near Field Pattern (NFP) - Intensity profile of the beam when measured at the front facet of the laser diode chip. Numerical Aperture (NA) - The numerical aperture describes the ability of a lens to collect light from a source placed at its focal point. The maximum acceptance angle q, is measured from the center axis of the cone of light to the outside or surface of the cone. Polarization Ratio - The output from a single cavity laser diode is linearly polarized parallel to the laser junction. Spontaneous emission with a random polarization and/or with a polarization perpendicular to the laser junction is also present. The polarization ratio is defined as the parallel component divided by the perpendicular component. For a diode operating near its maximum power the ratio is typically greater than 100:1. When operating near the threshold point, the ratio would be considerably lower as the spontaneous emission becomes more significant. Revised 02DEC98 (c) Optima Precision Inc. Phone: (503) 638-2525 email: sales@optima-optics.com url: http://www.optima-optics.com Optima(R) Laser Diode Application Notes and Glossary Single-mode Diodes - Laser diodes have either single or multiple longitudinal modes. For a single-mode laser diode the emission spectrum consists of a single spectral line occurring at the nominal wavelength of the device. At output levels near threshold, multiple spectral lines may be present in the emission spectrum however, these secondary lines decrease as the output increases. FAQ's and Laser Diode Basics: There are a number of precautions listed in the laser diode manufacturer's catalogs that should be observed when working with laser diodes. Below are a few points that might be helpful if you're new to this field: Safety Considerations - The laser beam emitted by the laser diode is harmful if aimed directly into the human eye. Never look directly into the laser beam or at any specular reflections of the laser beam. Electro-Static Discharge - Laser diodes are extremely sensitive devices and visible laser diodes (VLD's) tend to be the most sensitive type. The handling precautions outlined by the laser diode manufacturers are not overstated - good work habits require personal grounding straps and grounded equipment. ESD does damage laser diodes! Drive Circuits - Laser diodes should always be driven by either a Constant Current or Automatic Power Control (APC) circuit (the APC circuit may also be referred to as a Constant Power Mode circuit). For simplicity, an APC circuit is generally preferred, especially if the ambient temperature fluctuates. Typical circuits include slow-start or soft-start circuitry and provisions to ensure that spikes, surges, and other switching transients are eliminated. Regardless of type of circuit used, the drive current must not overshoot the maximum operating level - exceeding the maximum optical output for even a nanosecond will damage the mirror coatings on the laser diode end facets. A standard laboratory power supply is not suitable for driving a laser diode. Examples of the recommended drive circuits can be found in most manufacturer's laser diode data books. Unless you have prior experience with laser diodes and/or their drive circuits, this is not a place to reinvent the wheel - it can be very frustrating and expensive. Operating in Constant Power Mode vs. Constant Current Mode - The characteristics of a laser diode are highly dependent on the temperature of the laser chip. For instance, the wavelength of a typical GaAlAs diode will increase on the order of 0.25nm for a 1C rise in temperature. With a single mode diode, the change in wavelength may produce an undesirable effect known as "mode hops or mode-hopping". Other characteristics directly related to laser diode's operating temperature are; threshold current, slope efficiency, wavelength, and lifetime. Perhaps the most important characteristic is the effect of temperature on the relationship between the diode's optical output and the injection current. In this case, the optical output decreases as the operating temperature increases or, conversely the optical output increases as the operating temperature decreases. W ithout limits and safeguards built into the laser drive circuit, a wide swing in operating temperature could be catastrophic. However, there are two techniques commonly used to achieve a stable optical output from a laser diode: Constant Current mode combined with precise control of the diode's operating temperature is generally the preferred operating method. The constant current mode provides a faster control loop and a precision current reference for accurately monitoring the laser current. Further , in many cases the laser diode's internal photodiode may exhibit drift and have poor noise characteristics. If performance of the internal photodiode is inferior, the diode's optical output is likely to be noisy and unstable as well. Constant Current operation without temperature control is generally not desirable - if the operating temperature of the laser diode decreases significantly, the optical power output will increase and could easily exceed the absolute maximum. Constant Power or APC mode precludes the possibility of the optical power output increasing as the laser diode's temperature decreases. However, when operating in the constant power mode and without temperature control, mode hops and changes in wavelength will still occur. Further, if the diode's heat sink is inadequate and the temperature is allowed to increase, the optical power will decrease. In turn, the drive circuit will increase the injection current, attempting to maintain the optical power at a constant level. Without an absolute current limit thermal runaway is possible and the laser may be damaged and/or destroyed. Summary - for stable operation and maximum laser lifetime - temperature control and constant current operation is generally the best solution. However, if precise temperature control of the laser diode is not practical, then an APC circuit should be used. Revised 02DEC98 (c) Optima Precision Inc. Phone: (503) 638-2525 email: sales@optima-optics.com url: http://www.optima-optics.com Optima(R) Laser Diode Application Notes and Glossary Drive Circuit Precautions - Even when a laser diode is driven by a suitable drive circuit, watch for possible intermittent or unreliable connections between the laser diode and the drive circuit. An intermittent contact in the photodiode feedback circuit will very likely destroy the laser diode. One not-so-obvious component to consider is the power control. If a potentiometer is used for setting the laser diode's power, evaluate the circuit design to determine the failure mode if the potentiometer's wiper breaks contact with the resistive element. Also, never use a switch or relay to make or break the connection between the drive circuit and the laser diode. Power Measurements - The output from a laser diode must be measured with an optical power meter or a calibrated, large area photodiode. It's not practical or safe to estimate a laser diode's output power based on the diode manufacturers minimum-maximum data as each diode has unique operating characteristics and manufacturing tolerances. Remember, once the laser diode is past the threshold point, stimulated emission is achieved and the optical output increases significantly for a small increase in forward current. Therefore, a very slight increase in drive current may cause the optical output to exceed the absolute maximum. Even with a visible diode, it's not feasible to judge the laser output by eye, an optical power meter or calibrated photodetector must be used. Also, be sure to include optical losses through any lenses or other components when making measurements or calculations. Operating Temperature and Heat Sinks - In most applications, laser diodes require heat sinks especially when operated continuously (CW). Without a heat sink the laser diode junction temperature will quickly increase causing the optical output to degrade. If the laser diode temperature continues to rise, exceeding the maximum operating temperature, the diode can be catastrophically damaged or the long term performance may degrade significantly. Generally, a lower operating temperature will help extend the diode's lifetime as the laser diode's reliability and MTTF are directly related to the junction temperature during operation. VLD's with lower wavelengths, i.e. ~635nm, appear to be more sensitive to temperature and users might consider thermoelectric cooling if operating in an environment with elevated ambient temperatures or if operational stability is a prerequisite. Also, using a small amount of a non-silicone type heat sink compound will improve thermal conductivity between the diode and heat sink. Lifetime note: If the laser diode's operating temperature is reduced by about 10 degrees, the lifetime will statistically double. Windows - Keep the laser diode window, and any other optics in the path, clean. Dust or fingerprints will cause diffraction or interference in the laser output that can result in lower output or anomalies in the far-field pattern. The window should be cleaned using a cotton swab and ethanol when necessary. Cyanoacrylate Adhesive Precaution - "Super glue" should not be used anywhere near laser diodes - or near any other optical component - outgassing may fog windows and other optical surfaces. The amount of fogging, or the time required to observe the fogging, varies with different products. If you're in doubt, test the adhesive over time at an elevated temperature and in a sealed container. For example, place a drop of the adhesive in question on a piece of glass, something like a microscope slide, then place the sample in a plastic bag and seal the bag.
