Lithium fluoride (LiF) crystals belong to the cubic crystal system with (100) cleavage plane, and have excellent optical properties, especially in the deep ultraviolet band. With the development of deep-ultraviolet technology in recent years, LiF crystals have received more and more attention for their high transmittance and short cut-off wavelength in the deep-ultraviolet band.
