Ultraviolet Barium Fluoride (UV Baf2)

UV Barium Fluoride

Uv barium fluoride has an optical transmittance of 90% in the 200-9500nm spectral range. Lenses, splitters, filters, prisms and Windows used in cryogenic imaging systems, aerospace optical systems and laser optical systems. Barium fluoride products applied in the ultraviolet band require no obvious absorption in the range of 200-400NM, and the crystal structure can be single crystal or polycrystalline. The obtained UV barium fluoride is often closely related to raw materials, crystal growth preparation, crystal doping, and the finished crystal must meet the requirements of ROHS&REACH. Can be processed round, rectangular, open hole, meniscus, wedge Angle, flat convex, flat concave, double convex, double concave, open ball, prism.
