Uxcell Fiber Laser Protective Window Dia 50mm (1.97 ) Thk 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. First check the surface of the laser protection lens to see the smoothness of the surface. When installing the laser protection lens pay attention to the edge of the lens with your fingers and thumbs to ensure that the lens installed in the laser cutting head is clean. 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. Note: Do not touch the surface of the protective lens when installing the laser protective lens otherwise the dirty spots on the surface of the laser protective lens will be burned which will shorten the service life.
