Quartz Fused Silica Windows

https://www.lens66.com/products/quartz-fused-silica-windows/

Thin fused silica windows are processed through fine grinding, grinding, measuring, ultra-high-precision polishing and other processes. Under precise control of the machine tool and processing environment, ultra-high-precision correction polishing technology is used to polish the window surface to achieve an optical plane. Fused silica windows with surface accuracy ≤0.1 micron and surface roughness Ra≤0.01 micron
