Calcium Fluoride, Wafer, 99.999%, 30 mm dia x 2 mm th.

Calcium fluoride is widely used as a low-refractive index material for thin-film optical coatings, providing high transmission from the vacuum ultraviolet to the infrared spectrum.

Used as a high-purity source material in thermal and electron-beam evaporation processes to create protective and anti-reflective layers on optical components.

Calcium fluoride targets are utilized in physical vapor deposition to deposit thin films for specialized semiconductor and sensor applications requiring high moisture resistance and specific dielectric properties.
