Calcium Fluoride – CaF2 Lenses
We have own facility for Caf2 Lens. That is why we offer Calcium Fluoride (CaF2) lenses at very competitive price – up to 60% lower than major online optical catalogs!
CaF² is used for optical purposes as windows, prisms and lenses, transmitting from the vacuum ultraviolet into the infrared. Caf2 is a physically and chemically stable optical material with good water and chemical resistance. Two qualities are manufactured, one for Visible and Infrared applications and the other specifically for Ultraviolet applications grown from chemically pure powder.
Typically applications: VUV – UV – IR imaging systems, excimer laser windows, Spectroscopic windows and lenses, Optical Analysers, ATR crystals. Calcium Flouride is also available doped with rare earths; Europium activated is available for Scintillation detectors.
