UV lasers feature a short 355nm wavelength, often referred to as "cold processing." Unlike fiber or CO2 lasers that rely on heat to burn the surface, UV lasers break molecular bonds directly. This results in ultra-clean, high-contrast permanent marks with virtually zero heat-affected zone (HAZ), preventing any thermal distortion, charring, or warping of delicate plastics and PCBs.

Traditional UV lasers require a bulky external water chiller to regulate temperatures. This advanced 5W model utilizes a highly efficient air-cooling module. It eliminates the risks of water leaks, coolant refilling, and internal scaling. This significantly reduces the total package weight to just 25kg, lowers power consumption to a maximum of 500W, and requires zero routine cooling maintenance.

The system features a precise manual Z-axis column with a dual red-light focus indicator. During setup, you simply turn the lift handle until the two distinct red pointer dots merge perfectly into a single point on your material's surface, marking the absolute center of focus without requiring calipers.

While UV lasers are primarily designed for plastics, glass, microelectronics, and ceramics, they can easily mark metals with surface coatings or anodized layers by removing the layer with extreme resolution. For deep, bare metal engraving, a fiber laser system remains the industry recommended choice.

Yes. As an open Class 4 laser device emitting ultraviolet radiation at 355nm, operators must never stare directly at the beam or reflections. Anyone in the workspace during marking must wear certified OD6+ laser safety goggles specified for the 355nm wavelength, which are provided in the factory standard packing kit.
