    CaF2 Calcium Fluoride Crystals Optical Cubic Transparent In Wide Spetrum Band

    Calcium Fluoride—CaF2

    Description

    Calcium Fluoride (CaF2 or Fluorite) crystals are transparent in wide spectrum band. The product finds use in windows, lenses operating in UV and IR spectrum band. Laser Use: Calcium Fluoride is also used as a host lattice for laser crystals. Due to its composition, CaF2 has a much longer useful life than most materials when used in fluorine environment.

    Calcium Fluoride is used for optical windows, drilled discs, lenses and prisms in transmission range 0.15-9m. Degradation due to moisture in the atmosphere is minimal, and polished surfaces of the CaF2 windows may be expected to withstand several years exposure to normal atmospheric conditions. Since they are nonaxial, CaF2 crystals do not require consideration of axial direction.

    Because of CaF2 low refractive index, Calcium Fluoride windows can be used without an anti-reflection coating.Calcium Fluoride is attacked by atmospheric moisture at 600°C, where it begins to soften. The top use temperature is 800C, when moisture is not present. Irradiation of Calcium Fluoride windows causes some loss in UV transmission.
