LiF | Infrared Crystal is a type of cubic crystal which can be cleaved along 100 and less commonly 110. It has high optical transmittance from the vacuum ultraviolet to the infrared spectrum region (0.11 to 7μm) and shows excellent transmittance in the VUV regions. Modest precautions should be taken against moisture and high energy radiation damage. LiF is effected by atmospheric moisture at 400 °C and softens at 600 °C. It is sensitive to thermal shock and irradiation produces color centers.
