Product Description
CaF2 Plano-Concave Lens Facotry Products
Calcium Fluoride is used for optical windows, lenses and prisms in the transmission range 0. 15 µm to 9 µm. The refractive index varies from about 1. 7 to 1. 3 in this wavelength range. Calcium Fluoride is particularly popular for high power laser optics in the IR less than 6 micron because of its low absorbtion. Degradation due to moisture in the atmosphere is minimal, and polished surfaces may be expected to withstand several years exposure to normal atmospheric conditions. Due too its low refractive index, Calcium Fluoride can be used without an anti-reflection coating.

Calcium Fluoride is attacked by atmospheric moisture at 600C, where it begins to soften. The top use temperature is 800C, when moisture is not present. Irradiation of Calcium Fluoride causes some loss in UV transmission. The material is sensitive to thermal shock.
