Properties of the glass

A clean laser lens is imperative for the laser welding machine to work properly. Over time the protective lenses will be covered with dirt. Some of the dirt can be washed off, while others – such as welding splashes – burn into the glass. This reduces the efficiency of the laser over time. To prevent this it is wise to replace the protective lens on a regular basis.

The photo below shows a protective glass for laser welding. The glass will have a faint color reflection from the coating applied to the glass to optimize the transmission of the laser light at 1064 nm.
