Customized Barium Fluoride Infrared Optics Subsrate for Optical Scintillation Applications
Barium Fluoride is a salt compound of barium and fluorine. In crystal form, it is optically transparent over a wide range from the UV through to the IR and widely used to fabricate optical components. BaF2 barium fluoride scintillation crystals are characterized by a very fast scintillation emission with a decay time of 800 ps at 220 nm. The emission at 220nm has an emission with sub-nanosecond decay time interesting for timing applications.
