Product DescriptionLithium fluoride Window Filter for Laser LensesLithium fluoride crystals have excellent optical properties. Its transmittance range is 0.11um~7um, and it is used as a window, prism and lens in vacuum ultraviolet, ultraviolet, visible light and infrared optical syste ms. Due to their lattice structure, LiF crystals can also be used as X-ray diffraction elements.AdvantageInfrared transmittance: Excellent transmittance in the mid-to-far infrared band (2–8 μm), suitable for infrared optical applications.Low refractive index: Low refractive index (about 1.3–1.4), which can reduce optical interface reflection losses.Thermal stability: High melting point (about 800–1000°C), but lower than traditional oxide glasses.Chemical stability: Sensitive to water (easy to hydrolyze), need to be used in a dry environment.Applications of calcium fluoride components:Infrared optical devices: used in infrared windows, lenses, optical fibers (such as mid-infrared laser transmission).Nuclear technology: LiF itself has radioluminescence properties and may be used for radiation detection or scintillator materials.Laser technology: as a gain medium or optical element for some mid-infrared lasers.Special sensors: used for sensor protection windows in high temperature or corrosive environments.Technical Specificationssizes can be customized according to drawings.Transmittance range (μm)0.11~7.0Refractive index (5 μm)1.3943 (at 0.5um )Reflection loss 0.5 μm18.85x10-6K-hardness(kg/mm )158.3( 100 )Elastic coefficientC11=164;C 12=53;C44=33.7Solubility ( 9/100gH20·20°C)0.27Cleavage planes( 100)Density (g/cm )2.639Melting point (°C)870Multi system certificationHaving over 10 invention patents More than 50 utility model patentsIndustry UsersCompany ProfileLumistar Special Glass Technology Co., Ltd.Lumistar Special Glass Technology Co., Ltd. is a national high-tech enterprise mainly engaged in the research and development, design, manufacturing, and processing of various types of ultra-high pressure glass windows and safety protection equipment, including high temperature and high pressure glass, ultra-high pressure glass tubes, ultra-high pressure glass mirrors, ultra-low temperature glass, oil well ultra-high pressure glass blasting discs, sapphire glass, microcrystalline ceramic glass, pipeline mirrors, pressure vessel mirrors, high vacuum observation windows, ultra-high pressure alkali resistant mica glass mirrors, high pressure level gauge aluminum silicon glass, explosion-proof spotlights, bulletproof and explosion-proof glass, sintered mirrors, bulletproof security posts, and bulletproof transparent materials.FAQQ: Do you have a factory?A: Yes, we have a factory in Jiangsu.
