BARIUM FLUORIDE (BaF2) OPTICS

Barium Fluoride is used for windows, lenses and prisms, particulary when transmission into the ultraviolet is desired. The transmission range is from 0.2 to 11mkm. Transmission in the VUV is degraded by prolonged exposure to moist atmospher, but it is not significantly degraded by exposure to high energy radiation.

Barium Fluoride is less resistant to attack by water than Calcium Fluoride. Pronounced water attack occurs at 500C, but the material can be used to 800C to dry. Barium Fluoride is the most resistant fluoride to high energy radiation but does not have VUV transmission of other types. The material is relatively hard but is very sensitive to thermal schock.
