Calcium Fluoride Wafer Infrared Optics Window For a Range Of Laser, IR And UV Applications
Calcium Fluoride (CaF2) has good mechanical strength and moisture resistance, and it has a high transmittance in the band 0.15um~7.0um. CaF2 is widely used in laser, infrared, ultraviolet and high-energy detection fields. It is also a high-quality material for making optical components such as optical prism, lens and window. Its operating temperature under atmospheric pressure can reach 600℃, vacuum drying can reach 800℃.
