Barium fluoride (BaF2) has a near-90% transmittance in the wavelength range of 200–9500 nm. It boasts the widest broadband optical transmission, capable of transmitting from far ultraviolet to long-wave infrared, making it highly suitable for various applications, such as infrared spectroscopy. The low refractive index of barium fluoride, at 1.48, allows for high transmittance when combined with an anti-reflection film.
In a dry environment, calcium fluoride windows can endure up to 800 °C of ambient temperature, but prolonged exposure to water reduces their transmittance in the vacuum ultraviolet range. Compared to calcium fluoride windows, barium fluoride windows have lower moisture resistance but are more resistant to high-energy radiation, although they have lower UV transmission. The Knoop hardness of BaF2 is 82, and it is very sensitive to thermal shock. It is commonly used in cryogenic imaging systems, lenses in space optical systems, laser optical systems, beam splitters, filters, prisms, and windows. Due to its water solubility, BaF2 is best suited for dry environments. Its exceptional properties make it a valuable material in the field of infrared optics.
