LITHIUM FLUORIDE (LiF) OPTICS Alkor Technologies manufactures LiF windows, lenses and prisms according to customer's specifications. Maximum size of LiF optics: Dia:100 mm x 40 mm. Please contact us for more information.
Lithium Fluoride is used for windows, lenses and prisms in the vacuum UV, UV, visible and infrared where transmission in the range 0.104mkm to 7mkm is desired. Modest precautions should be taken against moisture and high energy radiation damage. LiF is attacked by atmospheric moisture at 400C, and softens at 600C. LiF is sensitive to thermal shock. Irradiation produces color centers. The material can be cleaved along (100) and less commonly (110). Although the optical characteristics are good the structure is not perfect and cleavage is difficult. VUV grade LiF windows are available. This is the best VUV transmitter available. Main properties:
