The CaF2 Crystal, or calcium fluoride crystal, is an ideal crystalline material for laser, IR and UV optics applications.
A CaF2 Crystal has a wide transmission range. Especially, it has high transmission in IR spectral region. Additionally, it is thermo sensitive and nearly undissolvable in water.
