LiF Lithium Fluoride Window

Processing Capacity

Capable to realize the complete processes in optical design, instrument design, component high-precision molding,

planar processing, spherical processing, aspheric processing, coating, etc.

Applications

Photoelectric information; aerospace; new energy; nuclear power and nuclear energy equipment and other fields.

Performance
● As a transparent physical barrier, the window allows light to enter from one environment to a different one.

● The material is Lithium Fluoride crystal, and its transmittance ranges from 105nm in vacuum UV to 6.0μm in IR. It

   is the material with the best transmittance in vacuum UV. Such crystals are widely used to make optical windows,

   lenses, prisms and reflectors in UV-VIS-IR field. Moreover, the crystal can also be used as an X ray detector crystal.

   Due to its low refractive index, the crystal can be directly used without anti-reflection and coating measures. As a

   window material, Lithium Fluoride crystal is an excellent achromatic and apochromatism material. It is widely used

   for prisms,UV and IR transmission window lenses in optical instruments.

● The surface reflection loss varies with the refractive index of the material when light penetrates the window .
