Calcium fluoride has a low absorption coefficient and a high damage threshold. Optical calcium fluoride provides low dispersion (Abbe number 95) and low fluorescence. Each window has a randomly oriented crystal axis.
Calcium fluoride (CaF2) is transparent in the ultraviolet to infrared (180 nm-8.0 μm) wavelength range. It has a refractive index of 1.428 at a wavelength of 1.064 μm, and has high mechanical and environmental stability. Calcium fluoride is very suitable for applications requiring low damage threshold, low fluorescence and high uniformity. It is commonly used in excimer lasers and spectrometers and cooling thermal imaging.
