yasioptics on 30 Jul 24Calcium fluoride (CaF2) crystals have excellent transmittance between 250nm and 7μm, which is widely used in makingbeam splitters, windows and lenses. lt has good transmittance in ultraviolet, visible and infrared waveband, so it is widelyused in the tielas of laser, ntrared otcs, ultravolet optics and hich energv detectors ect, ther optical proberies is especlallygood in UV waveband. CaF2 is known as the crystal at cut-off waveband of UV at present, therefore it is ideal material forultraviolet laser and ultraviolet optical system, Due to its low absorbance and high damage threshold, it has become an idealchoice for excimer laser optics, The low refractive index of calcium fluoride also enables it to be used without coating.
