Model LiF -Lithium Fluoride crystal

Lithium Fluoride crystal is the common optical material with minimum refractive, and its spectral range is 120nm-7000nm. Usually, it is processed to prisms,lenses and windows used for thermal Imaging System, Space optical system and excimer laser system. However, Lithium Fluoride crystal is with high aqueous solubility and coefficient of thermal expansion, which is need to special measures to prevent it from deliquescence and deformation.
