Optica l Probes for a Te ach ing Lab

There is growing concern over the science and math skills of today’s

students. So, the emphasis is to present these subjects in formats that

are mor e intere sti ng for t he student and easier f or the t eacher.

A new learning tool is available for kindergarten through college

students. It’s a microcomputer-based laboratory consisting of a base

unit, with various modules and probes, which attaches to a personal

computer and acts as the hub of a science lab. It helps to learn and to

teach science and math in new, more interesting ways by exploring

questions to reinforce the theory behind the answers. The modules

and probes connect to the base PC and allow for measurement of

temperature, lig ht, pH , di stance, etc.

PerkinElmer Optoelectronics provides the light measurement probes

used with this system. Two light probes are available: a photometric

probe and radi om etric probe.

The photometric probe uses a photometrically corrected photodiode

that provides a spectral r esponse to light similar to the hu ma n ey e. The

radiometric probe offers a radiometrically corrected photodiode

providing an absolute measurement of light intensity and a nearly

uni form sensitivity across the entire visible spectrum.

These assembl ies consist of a custom designed ph otodiode chip and a

custom glass filter in a hermetic package. This is assembled into a

waterproof housing, with a cable assembly providing connection to a

specific module. The finished assemblies are individually computer

calibrated usi ng a closely controlled light source. A filter holder is also

provided, allowing the introduction of additional filters into the light

path.

PerkinElmer is a certified supplier for this assembly. The units are

ship ped directly to retail distribution with no need for incoming Q.C. at

the cust om er ’s O.E.M. facility.

Sensors for X-Ray Detection

X-Ray security screening systems are seen in use wherever high

secur ity and rapid screening of large items are required. This includes

airports, customs facilities, nuclear power plants, correctional

institutions, corporate mailrooms, and government buildings. These

systems allow complete screening of luggage, parcels, boxes, crates,

etc.

Security screening systems feature powerful X-Ray units capable of

penetrating up to 17 mm of steel. The x-rays are sensed by spatial

arrays of photodiode detectors, positioned to allow two dimensional

sensing. Items passing through a tunnel opening are scanned and

imaged, with the images displayed on a video monitor in black and

white or in computer enhanced color.

Per kinElmer Optoelectronics provides linear X-Ray detect or arrays for

these security systems. These arrays produce the line sensing

capability used for the detection of the X-Ray images with less than

0.10 mR total exposure.

Each PerkinElmer detector array consists of four, eight element

common cathode photodiode arrays positioned end to end, providing

32 in-line elements, diebonded to a printed circuit board. The

photodiode arrays are custom designed specifically for this application

and are 100% te sted for light current and dark current. The arrays are

also 100% tested for response uniformity, which is the ratio of the

highest to lower light currents between the 32 detector element s. The

printed circuit board assemblies are manufactured to close

dimensional tolerances and are stackable end-to-end.

Optical Sensing Block for Medical Diagnosis

PerkinElmer Optoelectronics supplies sophisticated products to

med ical electronics . One example is a pair of hybrid packaged emitter-

detector arrays used i n a medical microbiology testing system. This in

vitro system is fully automated and offers the fastest microbiological

testing available. It shortens a patient’s hospital stay and allows the

physi cian to accurately and quickly select the most effective and least

e xpensive antimicr obial.

This automated diagnostic system has four components:

1. Disposable test kits , in cluding plas ti c cards used to identi fy

organism s and appr opriate antimicrob ials.

2. An inst ru m ent ca binet, containing a com put er, a mechanism for

inoculati ng test cards , and a reader/incubator that houses t he

Per kinElmer emitter and detector assemblies used to measure

the samples .

3. A data terminal and keyboard for communicating with and

controlling the system.

4. A printer for au tomatical ly r eporting final test resul ts.

Basi call y, t he PerkinElmer d ete ctor assembly consists o f a h ybrid arr ay

of precisely aligned phototransistor chips. These chips identify the t est

ca rd , and sense the atten uat ion of li ght passing t hr ough test card wells

cont aining enriched media and sample organisms. The light source is

a PerkinElmer emitter assembly consisting of a hybrid array of

precisely aligned light emitting diodes (LEDs). The testing system

controls temperature and timing exactly. The plastic cards are

automatically scanned hourly. The onboard computer interprets the

mea s ur em ent results and produces diagnostic reports.

PerkinElmer’s role in the design and manufacture of these critical

emitter and detector assemblies centers on quality workmanship and

sp ecia lly select ed discrete and mul ti -e lement opt o chips. A com par ator

is used for the precise alignment of the emitter and detector chips on

metallized ceramics, as well as for the precise alignment of the chrome

etched aperture cover glasses. The assemblies then undergo

extensive 100% computerized testing to assure perfor mance.

Optical Control of Photocopy Quality

Sensing toner density in photocopiers is a major application of

optosensors, PerkinElmer Optoelectronics has years of experience in

he lpi ng customers with hi gh per formance toner cont r ol sensors.

For example , one photocopier customer had an inf r ared density contro l

that had problems with accuracy and repeatability. A density control

reads a test patch on the photoreceptor and reports to the system

mi cr opr ocessor, which adjusts toner deli very and electrost ati cs.

We analyzed the existing assembly and determined that certain

as pects of optical performance had not bee n considered i n th e orig inal

design. Based on these findings, the optical housing was retooled to

pe rform to speci ficat ion.

Pe rkinEl m er also sol ved sev eral circuit pro blems . Temperature stabil it y

was improved by developing a higher shunt impedance detector. We

found that stability could be fur ther improved by changing the val ue of

the nulling pot for one of the op-amps. Noise problems were t raced to

an onboard voltage regulator. PerkinElmer recommended changing to

a ne w v endor and t he pr oblem w as eliminat ed.

An additional problem occurred when the assembly’s PC board was

bolted to a calibration fixture. The calibration readings tended to shift

due t o the stresses applied to the plastic packaged op-amp as the PC

bo ard was secur ed. Changi ng fro m a plastic to a rigid cer amic packa ge

IC resolved this problem, assuming that the sensor would remain in

ca li br ation during testing, shipping and handling.

Prior to PerkinElmer’s improvem ents, the customer had begun a major

design program to add diagnostic features onboard, allowing their

servicemen to perform field calibration. However, the customer’s field

ser vice calls, and the major design program was halted. This allowed

our customer to remain with the original design, and eliminate

calibration in the field—producing significant dollar savings.

Pape r Sensing in Ph otoc opy Machines

Paper is fed through a wide variety of office copiers and printers.

Automatic paper handlers need to sense the presence/absence and

position of the paper at the entry/exit ports of each operation in the

equipment. Reflective sensors like PerkinElmer Optoelectronics’

VTR24F1 are often used because they are non-contact sensors and

don’t interfere with the travel of paper through the machine. The

development of the original custom version of this sensor is a prime

example of how PerkinElmer can work with a customer from design

co ncept ion thro ugh final producti on.

The custo m er for this product origina ll y cam e to us with wh at appeared

to be a simple design request: design a low cost sensor to meet a

limited number of simple criteria. The finished device was to sense

white paper at a fixed distance from the sensor. The signal level

change had to fall within a certain range. We were given a target pr ice

an d a maximum physical si ze for the sensor.

The sensor w as de signed and demonst r ated. I t met al l design and cos t

goals. Tooling for the sensor case was committed and, upon

completion, pilot production devices were built. However, by the time

the evaluation was completed, the customer discovered that they had

missed some critical details in the original specification. They

determined that sensors would be needed in a number of additional

locations w it hin the machine and e ach had a diff er ent s pacing b etween

sensor and paper. They also determined that the sensor should “trip”

its output wi t hin a certain r ange (± 2 m m) of paper entry int o a specified

target area. Finally, it was required that black paper should be as

detectable as white paper. In total, parameters were added which

required 32 separate tests to verify function under all operating

conditions.

A redesign was done by PerkinElmer and all of the new specs were

met. A special computerized tested was designed to perform all 32

tests—quickly. As the product was moved into production, the

additional costs were gradually reduced through process design

modification and the unit price returned t o the original goal—in spite of

the large number of changes. Today, the unit price is lower than the

original goal and performance has been proven through hundreds of

thousands of parts and year s of service witho ut a f ailur e.

Notes On Using Reflective Switches

In its most basic form , a refle ctive optica l swit ch (retro ) cons ists

of a housing which holds both a light source and a detector. Light

from the lamp of LED radiates outward and is reflected back

should an object be placed in front of the switch. The reflected

light is sensed by the photodetector whose output signal

changes accordingly.

There are a number of different types of reflective sensors.

Designs vary depending upon the application. All have certain

characteristics in common. How well they detect an object

depends on:

1. Amount of light emitted by the light source.

2. Sensitivity of the photodetector.

3. Distance between the switch and the object being sensed.

4. The light reflecting properties of the object.

5 . A m bi ent lighting conditions.

6. The perpendicularity of the reflectiv e surface to the switch.

When the object to be sensed has a polished surface, such as

aluminum foil or mylar tape, often the best type of reflective

switc h t o u se i s on e wh ich is de si gned to ta ke advan tag e of t he

large am ount of directly ref l e cted li ght. Th i s i s do ne by mounting

the emitter and dete ctor su ch that their optical centers li e along

the legs of an isosceles triangle such that the angle of the

incidence of the emitter is equal to the angle of reflection.

Whe n tr yi ng t o se nse m att e obj ect s (wh ic h do no t have a hig hly

polished surface, such as white paper), it is often possible to use

a ty pe of ref lec tive swit ch op tim ize d fo r sen sin g dif fu se ref lec ted

light. Such devices have the emitter and detector mounted

p ar allel to each other wit hin th e swit ch ho using.

Sensor Used with a Specular Reflectance Su rface.

Sensor Used with a Diffuse Reflectance Surface.

Since triangulation is not necessary, the emitter and detector

elements can be located very close to each other. This allows for

a much smaller package than is usually possible for retros

designed to sense specularly reflected light. A retro designed to

sense diffuse d ref lected light ca n be the answer when space is

at a premium.

Standard Transmissive Optoswitches

Note s On Using S lott ed Switches

Effects of External Light

An IR transmitting plastic is used for the housing, providing a

sealed and seamless surface in the light path. Only visible light is

absorbed by the housing. Radiation with wavelengths longer

than 750 nm is transmitted. Fluorescent lamps primarily produce

visible light and the case provides adequate shielding for this

so urce o f stray li ght. H owever, i nca ndesc en t or su nl i g ht contains

significant amounts of long wavelength light and will cause a

su bst ant ial in cr ease in co llect o r cur ren t . Fo r thes e en vi ronm en ts,

the int erru pting vane s hould be designed to block light fr om the

IRED, as well as shield the detector from external stray light

sources. In extre me cases, the slo tted photo switc h may h ave to

be mounted in a light shielding enclosure.

Effects of Apert u res on Posit ion Res olution

Apertures can be installed inside the case to sense vane position

with higher resolution. Naturally, apertures also reduce output

current signal levels. The adjacent curves show how collector

current va ries as a thi n va ne is i nse rted i nto the center of the slot

of these optoswitches with no aperture, with various apertures

on the detector side only, and with apertures on both emitter and

detector sides.

When the vane is passe d very close to the dete ctor side, some

improvement in sharpness of change in collector current is

made. If the vane is close to the emitter side, performance is

degraded. The major improvement in position sensitivity,

∆

is obtained with apertures on both emitter and detector sides, but

at the expense of decreased output signal. Position sensing

resolution is only slightly increased as the aperture width is

directly reduced. With ver y small apertures on both emitter and

detector, stray light may become a significant portion of the

signal. Stray light may originate from external sources or from

light piping through the plastic housing. The major improvement

in performance is obtained with an .020 inch aperture on the

emitter side. Additional marginal improvements are obtained by

adding smaller aper tures on the detec tor s ide. When aper tures

are used on both the emitter and detector sides, performance

variations as the interrupting vane or wheel wobbles from side-

to-side in the sl ot are minimized.

Response Ti me

Response time is determined by the output device. The more

se nsit ive swi tch es have h igh er sensi ti vi ty t ransi st ors w hic h have

slower resp onse as i s shown in the response time graphs. The

response is much slower with high value load resistors. To

provide a suitable low resistance termination for fastest

response, use an external NPN transistor for current gain.

Quoted response time curves are for non-saturated switching.

Warranty Statement

PerkinElmer Optoelectronics’ business is the design, development, and production of optoelectronic components

and assemblies. Our development and manufacturing activities focus on achieving and maintaining consistent

product quality and high levels of reliability. PerkinElmer produces devices and assemblies for the commercial,

industrial, automotive, and medical markets.

PerkinElmer ’s commitment to quality emphasizes designed-in quality, problem prevention, and closed loop

corrective action. This concept of quality is implemented through the use of fully documented procedures, in-

process monitoring and process control (including SPC), and 100% production testing of devices using state-of-

the-art automated test equipment. As a world class manufacturer, PerkinElmer ’s concept of product quality

includes Total Quality Management (TQM) and Just In Time (JIT) delivery.

Quality is a measure of how well a device conforms to its specifications. Reliability is a measure of how well a

device performs over time. PerkinElmer insures the reliability of its products by careful design and by the

periodic testing of random samples taken from the manufacturing lines. Reliability tests include temperature

cycles, thermal shock, room ambient life tests, elevated temperature life tests, high and low temperature

storage, temperature/humidity tests, and water immersion.

PerkinElmer also performs special tests covering a wide range of environmental and life stress conditions to

support non-standard, custom applications. The information generated not only assures the customer that the

device will work well in a particular application, but also contributes to our data base for continual product

improvement.

Driven by our goal of continuous improvement and the needs of customers, PerkinElmer runs an active product

improvement program. PerkinElmer continuously evaluates new materials, manufacturing processes, and

packaging systems in order to provide our customers with the best possible product.

PerkinElmer ’s quality works: we are an ISO 9000 and QS 9000 certified supplier (ship to stock - no inspection

required) to a number of major customers.
