Barium Fluoride crystal
For windows, lenses, prisms

BaF2 crystal have a good optical transmission properties in the spectral range of 0.15μm-12.5μm, it can be used as ultraviolet and infrared optical window. Meanwhile, BaF2 is usually used as scintillator for gamma detection. It is the fastest scintillating crystals up to now. It become the important cystal material in the field of High Energy Physics and Nuclear Physics, Nuclear Medicine. 


Barium fluoride (BaF2) crystal: The largest diameter is 160mm; the greatest length is 350mm.
