Round Quartz Glass Sheet for Optical Experiments U-V Transparent, High Permeability and Thermal Stability (1 mm x 4 mm)

Round quartz glass sheet material: quartz material (JGS-2)/round quartz glass sheet Usage: various optical experiments. Quartz window lens specifications: (thickness 1mm); (diameter 4mm-45mm); Tolerance: plus or minus 0.1mm; Transmission: >93%; Finish: 60/40; Applicable wavelength: 220nm-2500nm; Round quartz glass sheet has good thermal stability, low thermal shrinkage coefficient, and can withstand violent temperature changes. It will not burst in water at normal temperature 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 easy to corrode, besides hydrofluoric acid, quartz glass almost does not react with other acids and its acid resistance is 30 times that of ceramic and 150 times that of stainless steel. Quartz glass has good transmission throughout the spectral band from ultraviolet to infrared, and the visible light transmission is more than 93%, especially in the ultraviolet spectral region, the maximum transmission can reach more than 80.
