Barium Fluoride (BaF2) Single Crystal Substrate

Barium Fluoride (BaF2) Single Crystal Substrate

Application:
BaF2 is widely used as a scintillator material for high-energy physics due to its fast scintillation component. It is also an excellent optical window material for infrared (IR) and ultraviolet (UV) spectroscopy, and thermography, thanks to its wide transmission range.

Product Overview:
This product features high-quality Barium Fluoride (BaF2) single crystals grown via the Crucible Descent Method (Bridgman technique). It offers excellent transmission from vacuum ultraviolet (VUV) to infrared wavelengths and is characterized by its cubic structure and resistance to high-energy radiation.
