Description

Calcium Fluoride(CaF2) optical Crystal is widespread used in applications of Ultraviolet(UV),Infrared(IR) and visible light, like optical windows, optical lens and thermal imagining, it has wide transmissive range from 0.13um(UV) to 10um(IR) and low refractive index. Calcium Fluoride’s combination of low absorption with a high damage threshold makes it an excellent material for use with Excimer lasers.
