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.

Zinc sulfide (ZnS) exists in two material forms: a white multispectral material and a yellow virgin material. Both are chemically inert, featuring high purity, insolubility in water, moderate density, and ease of processing. Due to its broad transmission wavelength range (500–10000 nm), zinc sulfide (ZnS) is widely used in manufacturing infrared windows, domes, and infrared optical components.
