Commercial Grade CaF2 Windows
Commercial Grade CaF2 Windows
Product name : Commercial Grade CaF2 Windows
Description :
CaF2 is often used in spectroscopic windows 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.
