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