CaF2 Windows

11 Dec 2012

Calcium fluoride is often used in spectroscopic windows and lenses due to its high transmission from 250nm to 7µm. Its low absorption and high damage threshold makes it a popular choice for excimer laser optics. Calcium fluoride's low index or refraction allows it to be used without an anti-reflective coating.
