Stanford Advanced Materials (SAM) offers crystal Lithium Fluoride Crystal Substrates and provides customers the widest choice of LiF material with high uniformity of electrical properties and excellent surface quality.
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.

I'm very pleased with these so far, as a substrate for film coating at high temperature.
