HG Optronics, Inc. LiF crystal lithium fluoride

HGO grows LiF crystals in house using Czochralski technology. LiF crystal or lithium fluoride crystal is an optical material with outstanding transmittance in VUV region. It is also used for windows, prisms, and lenses in the visible and infrared in 0.104µm-7µm. LiF single crystal is sensitive to thermal shock and would be attacked by atmospheric moisture at 400°C. When working at a high temperature of 600°C, the LiF crystal softens and is slightly plastic, so it can be bent into radius plates. In addition irradiation produces color centers. Hence, users should take measures to protect LiF crystals from moisture and high energy radiation damages. What is more LiF 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. Descriptions: HGO grows LiF crystal lithium fluoride. LiF crystal or lithium fluoride crystal is an optical material with outstanding transmittance in VUV region. It is widely used for windows, prisms, and lenses in the visible and infrared in 0.104µm-7µm. Main application: 1) X-ray monochromator plates UV photomultiplier tubes 2) Optical material for VUV applications 3) Windows, prisms, and lenses Main Features: 1) Tends to create color centers. 2) Max temperature for application:400°C 3) Excellent VUV region transmittance 4) Sensitive to thermal shock Why Choose HGO ? HG OPTRONICS.,INC. is one of few growers who LiF crystals in house. The use of high quality starting materials for crystal growth, whole boule interferometry, precise inspection of scattering particle in crystal using He-Ne laser and delicated measurement of bulk losses using spectrophotometer assures that each crystal will comply with customer’s specification and perform well. In addition, we can also produce other types of window crystals like YAG crystals, BaF2,MgF2 Crystals, etc.
