C-Lens

Micro Optics >>> C-Lens

C-lens are specifically designed for fiber optics applications such as collimator, isolator, switch, collimator array and laser assembly. Compare to other gradient index lens, C-lens have several advantages including low cost, low insertion loss in long working distance, and wide working distance range. With our experienced optical design engineers, Red Optronics can also provide custom designed C-lens per customer's requirement.
