Barium fluoride for IR(high transparency)/ flicker (low background) applications in high-energy physics, multispectral cameras, infrared thermometry and thermal imaging.
It has the advantages of wide spectrum, large supply and low price. It can be used as windows, flat films, domes, lenses, prisms, etc., and has a wide range of applications in FTIR, LWIR, hyperspectral cameras and other fields.
Barium Fluoride (BaF2) Window can be used in a variety of applications, such as infrared spectroscopy, due to their wide broadband transmission that extends from the deep ultraviolet to the long-wave infrared. Barium fluoride’s low index of refraction of 1.48 provides high transmission without the need for anti-reflection coatings. barium fluoride windows can be used up to 800°C in a dry environment, but prolonged exposure to moisture can degrade transmission in the vacuum ultraviolet range. While barium fluoride windows are less resistant to water than calcium fluoride, BaF2 windows are the most resistant optical fluoride to high-energy radiation, but feature lower UV transmittance. BaF2 has a Knoop hardness of 82.
