Blue Laser Collimating Aspheric Glass Lenses
Blue Laser Collimating Aspheric Glass Lenses
Our Blue Laser Collimating Aspheric Lenses are designed to simplify the design and implementation of laser systems for biomedical instrumentation including flow and imaging cytometers, fluorescence detection, and high volume data storage systems.
These aspheric lenses are designed and manufactured to meet stringent optical standards for the aforementioned high performance applications. Each aspheric lens is delivered with a high performance anti-reflection coating to provide optimum transmission in the 400 – 700nm wavelength range.
Application
- Industrial and automotive alignment laser for small dimension
- Laser collimated for hand-held positioning and sensing
- Small dimension/short focal length requirement for optical design
- Application in high temperature or adverse circumstance
- Designs Optimized for 405nm and 445nm Laser Diodes
