Calcium Fluoride (CaF2) Lenses
CaF2 lenses are available in UV/IR & UV Monocrystalline & Polycrystalline. They are widely used in infrared and ultraviolet spectral ranges for applications requiring elevated transmission. Its exceptionally elevated threshold for laser damage makes it beneficial for laser applications. The material displays a small refractive index ranging from 1.35 to 1.51 within its 180 nm to 8.0 μm. Calcium fluoride material is robust and may be expected to withstand several years’ exposure to normal atmospheric conditions. AR coatings are available for UV and IR wavelengths.
We offer standard stock sizes and custom ranging from 5mm to 100mm diameter.
