1. C-Lens

C-lens is specially designed for fiber optics applicaton in collimator, isolator, switch, collimator array and laser Assembly. Compare to gradient-index lens, C-lens has many advantages including low cost, low insertion loss in long working distance, wide working distance range. With our experienced optical design engineers we also provide the designing of c-lens according customer's requirements, beside our standard products listed below..
