Description
Axetris' laser diode collimation micro-lenses are designed and optimized for efficient collimation of edge emitting laser diodes (LDs) and vertical cavity surface emitting lasers (VCSELs). Applications include collimation of laser diodes and focussing onto photodiodes for optical fiber communications and optical sensing.
