Product DescriptionGermanium glass Window Filter for Laser LensesGermanium crystals of 2-14 microns have good light transmittance and are widely used in thermal imaging systems for windows and optical components. The germanium glass used on the window of the infrared thermal imager and infrared thermometer is mainly considered to be only 40-50% in the 8-14um wavelength band without coating,while the transmittance can reach 90% after the anti-reflection coating is plated.Moreover,most customers will also require DLC diamond-like carbon film to be plated in germanium glass,which is used to strengthen the hardness of germanium glass and play a certain explosion-proof effect. AdvantageTransmission range:Infrared band: covers 2–16 μm (mid-far infrared), especially excellent performance in the 8–12 μm atmospheric window.Opaque to visible light: completely absorbs visible light (0.4–1.8 μm), with a gray-black metallic luster.Refractive index: high refractive index (~4.0), anti-reflection coating (such as ZnS, MgF) is required to reduce reflection loss.Applications of calcium fluoride components:Thermal imaging systems: infrared lenses and windows (military night vision devices, security monitoring thermal imagers).Laser optics:Lenses and reflectors for CO lasers (10.6 μm).Optical components for mid-infrared laser systems.Aerospace and remote sensing: optical components for satellite infrared sensors and onboard spectrometers.Fiber optic communications: end couplers for mid-infrared optical fibers (such as chalcogenide glass fibers).Technical Specificationssizes can be customized according to drawings.Element symbolsGEAtomic coefficients 32Melting point (°C)1520Knoop hardness kg/mm112Young's modulus GPa103Static bending strength (MPa)≥75Poisson's ratio0.28Multi 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.
