Description

Lithium Fluoride Crystal Substrates Description

Lithium Fluoride Crystal Substrates (LiF) belong to the cubic system, and the cleavage plane is the (100) plane, which has excellent optical properties, especially in the deep ultraviolet range. With the development of deep ultraviolet technology in recent years, Lithium Fluoride Crystals are widely used for deep ultraviolet, due to its high transmittance in the deep ultraviolet region and short cutoff wavelengths.
