Fused quarts at 200nm to 2.2um has high transmittance and low coefficient of thermal expansion, which makes it an ideal choice for spherical lens with strict requirements in ultraviolet, visible and near-infrared spectral applications. Spherical lenses are commonly used to ...
High temperature resistant clear quartz glass plate Quartz glass has a very low coefficient of thermal expansion, high temperature resistance, excellent chemical stability, excellent electrical insulation, low and stable ultrasonic delay performance, the best UV-Vis spectral ...
Fire Resistant Quartz Glass Fused Silica Plate For Camera A method for producing a large-diameter silica glass is to put quartz sand raw material into a crucible of a melting furnace, reduce the crucible to a minimum through the upper cover, and melt the molten material into a ...
