UV laser markers use ultra-violet light, typically at a 355 nm wavelength, to mark or process materials. This wavelength, about a third of the typical fibre, allows the UV laser to do things that no other laser marker can. The shorter wavelength delivers significantly higher absoption and a much smaller beam spot. This allows for high contrast and damage free marking on metals and plastics, and the ability to mark smaller or more precise parts. This makes it an ideal solution for heat sensitive materials or parts requiring precision that typical fibre lasers cannot achieve.
Applications:
It is used in very small spot size markings on metallic surfaces. In addition, it includes steel, aluminum, stainless steel, polymers, silicon, glass, rubber, and others.
Usually, high-precision engraving and marking of all plastic materials, as it doesn’t affect or melt the surfaces.
LED bulb markings with serial number, codes and other information.
Used in high-resolution glass marking at cost-effective rates and appealing designs.
Specified shapes and areas marked on the wood.
Leather marking and engraving.
Garment industries use this for high-quality marking.
Ceramic marking and engravings are precise and with high-speed and high resolutions.
Marking and engraving of some popular stones, i.e., granite, marble, and slate.
UV laser machines are helpful in marking and engraving of paper and paperboard at high speed.
