UV Lithium Fluoride

Ultraviolet lithium fluoride is an application material in the field of ultraviolet optics. Its chemical formula is LiF and it belongs to alkali metal halides. At room temperature, it is a white crystal that is insoluble in water. Its structural formula is body centered cubic, with a relative density of 2.640, a melting point of 848 ℃, and a boiling point of 1681 ℃. The transmittance ranges from vacuum ultraviolet 110nm to infrared 6.0 μ m. Can be used as optical windows, lenses, prisms, and refractive elements. As an optical crystal manufacturer, we can also customize optical crystals with different shapes and specifications according to your needs. If you have any questions or needs, please feel free to consult online.
