WEAREONE Quartz Window Lenses Round Quartz Glass Sheet High Permeability High Temperature Resistance UV Transparent Quartz polishing Sheet for Optical

✨Round quartz glass sheet material: Quartz material (JGS-2)/Round quartz glass sheet Use: various optical experiments. ✨Quartz window lens specifications: (2mm thick); (diameter 8mm-45mm); Tolerance: plus or minus 0.1mm; Transmittance: > 93%; Finish: 60/40; Applicable wavelength: 220nm-2500nm; ✨Quartz glass has good transmittance in the entire spectral band from ultraviolet to infrared, and the visible light transmittance is more than 93%, especially in the ultraviolet spectral region, the maximum transmittance can reach more than 80. ✨The round quartz glass sheet has good thermal stability, small thermal shrinkage coefficient, and can withstand violent temperature changes. It will not burst into normal temperature water and can work for a long time at about 2012 degrees Fahrenheit. The temperature can reach about 2642 degrees Fahrenheit for short periods of use. ✨Round quartz glass is not easily corroded, in addition to hydrofluoric acid, quartz glass almost does not react with other acids, and its acid resistance is 30 times that of ceramics and 150 times that of stainless steel. ✨Quartz material (JGS-2) ultraviolet quartz glass: quartz glass produced with quartz raw materials and chlorine oxygen flame contains a few +PPM of metal impurities; there is an absorption peak at 2730NM (light base content 100-200PPM); there are stripes and star structure; it is a good material in the band range of 220-2500 PM

✨Quartz glass has a high hardening temperature and can be used for a long time. In particular, the chemical stability at high temperatures is unmatched by any other engineering materials. Quartz glass electrical insulation performance is good, its resistance value is equivalent to 10,000 times of ordinary glass, is an excellent electrical insulation material, even at room temperature also has good electrical properties.
