Lithium Fluoride (LiF) shows excellent transmittance in the range of 110nm to 7μm, transmission between these ranges is over 90%, VUV, visible and optical windows, optical lenses, optical mirrors and so on. It is widely used in IR spectrum applications. LiF crystals sensitive to heat shock and decompose with atmospheric moisture at 400 ° C and soften at 600 ° C. The material can be separated along the 100 and less frequently 110. Although the optical properties are good, the structure is not perfect and difficult to divide. The high quality LiF is usually grown with a modified Bridgman technique.
1. Excellent transmission from 110nm to Excellentm
2. Optically isotropic, medium hard
3.Insoluble in water
4.Sensitive to thermal shock
