C-lens are specially designed with special
material and profile for collimator used in fiber optics.
This Micro lenses can transform the light from single mode
fiber into a collimating beam in lower loss. In reverse,
Micro lenses also can as a coupler from collimating beam
into fiber. Micro lenses can be designed for collimator
at different working distance, particularly at long working
distance. CRYSTECH provide to manufacture C-lens on custom
designing herself and standard specification.
