UV Laser Marking Machine 3–10 W (355 nm)

Overview

A UV laser works at 355 nm, a third of the wavelength of a fiber laser. At this wavelength the mark is made mainly by photochemical action: the laser energy breaks the bonds between molecules, and the material leaves the surface as small fragments. Very little heat spreads into the part. The focused spot is also very small, which is why UV is the usual choice for ultra-fine marks.

The result is a crisp mark on materials that a fiber laser would melt, burn or discolour: clear and coloured plastics, glass, crystal, silicon, flexible PCBs and coated surfaces. UV also marks most metals for fine surface work.
