Alfa Chemistry offers a wide range of barium fluoride (BaF2) optical components for UV and IR applications. BaF2 transmits from UV to IR, from 150 - 200 nm to 11 - 11.5 μm, and can be used as a material to make optical components such as windows, lenses and prisms. The highest quality BaF2 can also be used as the fastest known scintillator material and is used in high energy physics experiments. It reacts to X-rays, gamma rays, and other high-energy particles. It has several scintillation emission bands. The fast one is centered at 220 nm with an attenuation constant of 0.6 ns; the slow scintillation band is centered at 310 nm with an attenuation constant of 620 ns.
BaF2 has good transmittance in the range of 0.2 to 11 μm. It is very sensitive to mechanical and thermal shocks. It can be used for infrared laser applications. BaF2 is less water resistant than calcium fluoride (CaF2), but can still be used in dry air up to 800°C.
