CaF2 Windows

CaF2 Windows are made from Calcium Fluoride material, which has transparent range from 170-7800nm. The refractive index is 1.399 at 5000nm. It has little hygroscopic susceptibility and high thermal expansion coefficient. CaF2 Windows are relatively soft and somewhat hygroscopic so polishing, coating and handling are more critical than UV Fused Silica windows. Beside UV application, CaF2 also is commonly used in IR components such as windows, Lenses and prisms.
