Lanthanum Fluoride powder is available as a 99.99 pure (metals basis) powder in large batch quantities for use optical components such as ultraviolet dichroic and narrowband mirrors. Lanthanum Fluoride is transparent in the far ultraviolet making it an ideal compound in multilayered optical components that require a high index of refraction. Additionally, this material can be used as a laser host or may be doped with Europium at 0.3% for a fluoride-ion selective electrode. Lorad Chemical uses a precise manufacturing process with controlled stoichiometry to produce large batch quantities of consistently high-purity powder for even the most sensitive applications.
