Uxcell Fiber Laser Protective Window Dia 20mm (0.79") Thickness 2mm (0.08") Fused Silica Quartz Lens for Laser Welding Machine

The fiber laser protective window is made of special industrial technology glass quartz made of silica, which has high-temperature resistance, corrosion resistance, low thermal expansion coefficient, thermal shock resistance, good electrical insulation performance, and good thermal stability. Both sides of the protective laser lens are coated with an anti-reflection film to reduce high damage to reduce the loss caused by reflection. The double-sided anti-reflection film processed is section, rounded, polished, polished, and coated. It has stable performance and is durable.
