With a transmission range from 130 nm in vacuum ultraviolet to 9 m in the far infrared, calcium fluoride crystals are widely used in optical devices such as windows, lenses and edges in the vacuum ultraviolet to infrared spectrum. Due to their low absorption, calcium fluoride crystals are also used in high-power laser optics. In general, the polished surface of calcium fluoride is very stable and can be used for many years. In addition, the low refractive index allows the crystal to be used directly without an anti-reflective coating.
It is a good ultraviolet and infrared high transmittance material, and can also be used as an achromatic lens.
1)The transmittance of all CaF2 window pieces/polishing pieces is greater than 93%
Features: Good light transmittance, 200nm-8um transmittance greater than 93%, less impurities and less deliquescence.
All self processed, self polished, with good consistency in surface finish and shape!、
