CaF2 (Calcium Fluoride) crystal is not only a conventional but also an excellent material for the applications of laser optics. The crystal covers a very wide transmission range from 130nm to 9500 nm (UV, VIS and IR), especially, features a high transitivity in IR range. Those advantages make CaF2 an ideal material widely used in Laser, IR and UV optics for making optical windows and lenses, etc

CaF2 crystals have the following exceptional properties that make it a very important optics crystal:

(1) High optical transmittance from the vacuum ultraviolet to the infrared spectrum region(0.13-11μm).

(2) Used for Optical prisms, lenses, wedges, windows, other optical components,and etc.
