Calcium Fluoride( CaF2) windows can be used for Ultraviolet (UV) through to Infrared (IR) applications, due to its transmission range from 160nm up to 8 microns.
Calcium Fluoride offers Low Absorption and High Transmission. UV Grade Calcium Fluoride can be used down to 160n
IR grade can be used for Applications Ranging from 250nm through to 8?m
Calcium fluoride's low refractive index allows it to be used without an anti-reflective coating.
Windows manufactured from vacuum UV grade calcium fluoride are commonly found in cryogenically cooled thermal imaging systems.
We manufacture CaF2 windows in a wide varietyofsizes, and can easily produce to your exact dimensions.
