PROTECTION WINDOW FOR CO2 LASER MARKING MACHINE
In order to protect the scanning lens from harming by spatter and other hazards in the workplace, we provides a protection window (also known as the anti fragmentation window) which can be provided either as a part of the scanning mirror component or can be sold individually. These windows are made of zinc selenide and germanium. The Znse protection window is coated with AR coating or DAR coating. Germanium protection window is coated with AR coating or optional diamond-like carbon coatings (DLC), which can be used in the worst industrial environment. The size listed are the ones used commonly.
