Barium fluoride (BaF2) crystal belongs to cubic crystal system, good moisture resistance, melting point 1280 °C, high using temperature, the refractive index does not change much in a wide wavelength range and with a wide of light transmission range. The highest transmittance can reach  >90% in the wavelength range of 0.2μm to 10μm. BaF2 crystal has good optical and mechanical properties.

 

In addition, BaF2 crystals also have excellent scintillation properties (due to their fast and slow 2 luminescence components, the crystal can simultaneously measure energy spectrum and time spectrum, Moreover, the energy resolution and time resolution are relatively high. ), so the BaF2 has broad application prospects in the fields of high energy physics, nuclear physics and nuclear medicine.
