Calcium Fluoride is used for lenses in transmision range 0.15-9mkm. Degradation due to to moisture in the atmosphere is minimal and polished surfaces of the CaF2 lenses may be expected to withstand several years exposure to normal atmospheric conditions. Because of CaF2 low refractive index, Calcium Fluoride can be used without an anti-reflection coating.
