CaF2 Window

Calcium Fluoride is used for optical windows, drilled discs, lenses and prisms in transmision range 0.15-9µm. Degradation due to 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.

Typical applications: VUV - UV - IR imaging systems, excimer laser windows, CaF2 viewport, Spectroscopic windows and lenses.We produce CaF2 windows and mirrors for European manufacturers of gas detectors and gas analyzers.
