We use the pulling method to grow high-quality lithium fluoride. The transmittance of lithium fluoride crystals ranges from 105nm in vacuum ultraviolet to 6.0μm in infrared, which is the material with the best vacuum ultraviolet transmittance. This kind of crystal is widely used to make optical windows, lenses, prisms and refractive elements in the ultraviolet-visible-infrared field. In addition, this crystal can also be used as an X suspected detector crystal. The low refractive index allows the crystal to be used directly without anti-reflection coating. As a window material, lithium fluoride crystal is an excellent achromatic and polychromatic material, which is widely used in ultraviolet and infrared transmissive window lenses and prisms in optical instruments.


Fast Silver offers various infrared crystal material:Lithium fluoride, Al2O3, MgF2, CaF2, Germanium.
