The Collimator Lens is used in the beam transfer system to maintain the collimation of the beam between the laser resonant cavity and the focusing optical element.
Collimator Lens has the characteristics of small divergence, high parallelism and uniform distribution of light spots.
Collimator Lens can be divided into reflection and transmission collimator. The reflective collimator is used in copper mirror, and a transmission type collimating lens using ZnSe lens.
We can also supply the Blue Laser Module, Mini Laser Module etc. Welcome to contact us.
