C-lens is specially designed for fiber optics usage in collimator, isolator, switch, collimator array and laser embly. Compare 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 our experienced optical design Engineers we also provide the designing of c-lens according customer's requirements, beside our standardproducts list here.
