Features
Recommended Applications
● High numerical aperture achieved via aspherical design
● Short focal length for compact size
● Appropriate lenses and lens material available for many different applications
● Wide temperature and humidity range for increased reliability and stability
● High-quality processing,measurement techniques and precision manufacturing process
give less variation in optical properties
● RoHS compliant
✽ We can offer custam design,sampling and mass production as requested
● Collimator lens for laser beam printers
● Coupling lens for optical communication systems
● Collimator lens for optical communication systems
These products are aspherical glass lenses by using a
press molding,
and key devices of optical electronics not only provide
compact and light weight but also high-performance
by utilizing characteristics of aspherical design.
