These micro C-lens are specially designed for applications
such as collimator, isolator, switch, collimator array and laser Assembly.
Comparing to gradient index lens, C-lens has advantages including low
cost, wide working distance range, low insertion loss especially in long

Spherical ball lenses are commonly used for laser collimating and focusing,
laser-to-fiber coupling, fiber-to-fiber coupling, and fiber-to-detector coupling.
Diameters from 1mm to 8mm are available. Additional AR coating to the ball lens is
