BaF2 window crystals or Barium Fluoride window crystals, with their extremely broad transmission range from the deep UV to LWIR spectrum, are prevalent for Infrared applications
requiring additional transmission in the Ultraviolet region. BaF2 window crystals are excellent when being used for IR spectroscopes and as viewport windows for thermal imaging inspection
in electric power facilities and petroleum industries. A low refractive index of 1.48 implies BaF2 windows have high transmission rates without anti-reflection coating.
BaF2 window crystals has similar properties to CaF2, the difference mainly lies in that barium fluoride window is more resistant to highly energetic radiation, and with an equivalent
thickness, the transmission range of BaF2 window extends approximately 1 micron further into the long-wave IR region than calcium fluoride. BaF2 window crystals could also accommodate
high-temperature environments up to 800 ℃. However, exposure to moisture will increase its sensitivity to temperature and reduce its
transmission rate to UV lights. If you would like to know more about BaF2
