C-lens are specially designed with special material for collimator used in fiber optics. This C-lens can transform the light from single mode fiber into a collimating beam in lower loss. In reverse, C-Lens also can as a coupler from collimating beam into fiber. C-lens can be particularly designed for collimator at different working distance.
