Fused quartz windows have excellent optical quality, low coefficient of thermal expansion, and transmission over 80% at a wavelength range of 260nm to 2500nm. Fused quartz is harder than glass and can be used at temperatures up to 1050°C. Fused quartz windows are widely used in scientific research and many commercial and industrial applications due to their durability, high chemical resistance, high thermal stability, and low cost. Shanghai Optics can produce custom fused quartz windows with a large diameter size and thickness.
