Calcium Fluoride is used for optical windows, lenses and prisms in the 0.15μm - 9μm range.

This material has found wide use in high power laser optics due to its low absorption. Polished surfaces are stable and will last several years under normal conditions. Due to its low refractive index, Calcium Fluoride can be used without anti-reflection coating.

Calcium fluoride is grown by vacuum Stockbarger technique. Material for IR use is grown using naturally mined fluorite, in large quantities at relatively low cost.
