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, UNI OPTICS can also provide custom designed C-lens per customer's requirement.

Laser beam collimation Lens
Laser Lenses are used to focus collimated light from laser beams in a variety of laser applications. Laser Lenses include a range of lens types including PCX Lenses, Cylinder Lenses, or Laser Generator Lenses. Laser Lenseare designed to focus light in several different ways depending on the lens type, such as focusing down to a point, a line, or a ring. Many different lens types are available in a range of wavelengths.
