Barium fluoride crystal shows good optical transmittance over wide spectrum range, from 150nm to 12.5μm. It is used for windows, lenses and prisms, particularly for the application of ultraviolet transmittance. The highest quality of BaF2 has an application as the well know scintillation crystal.
Opticreate provides UV grade and IR grade BaF2 windows and lenses.
