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