[delmarphotonics]

Del Mar Photonics offers variety of optical components from VUV grade and IR grade Lithium Fluoride.
Lithium Fluoride is used for windows, lenses and prisms in the vacuum UV, UV, visible and infrared where transmission in the range 0.15µm to 6µm is desired. The refractive index varies from about 1.4 to 1.3 in this range. These crystals are optically isotropic, middle hard, unsolubale in water. Modest precautions should be taken against moisture and high energy radiation damage. LiF is attacked by atmospheric moisture at 400° C, and softens at 600° C. LiF is sensitive to thermal shock. This is the best VUV transmitter available.
