LiF Infrared Optics Used For Windows, Prisms And Lenses In Visible and Infrared Range

LiF crystal has excellent VUV region transmittance. It is used for windows, prisms, and lenses in the visible and infrared in 0.104 um - 7 um. LiF crystal is sensitive to thermal shock and would be attacked by atmospheric moisture at 400°C. In addition irradiation produces color centers. Modest precautions should be taken against moisture and high energy radiation damage. Besides LiF softens at 600°C and is slightly plastic that can be bent into radius plates. The material can be cleaved along (100) plane and less commonly (110) plane. The optical characteristics are good and yet the structure is not perfect and cleavage is difficult. For good structure LiF is less commonly grown by the Kyropoulos method (air-grown) specifically for monochromator plates. High quality LiF is usually grown by modified Bridgman method.
