Short description
3W UV lasers use a highly absorbent wavelength of 355 nm and are better captured by virtually all materials than other wavelengths and marking techniques. 3W UV laser requires less power to produce a clear mark. Less power and a high absorption rate allow 3W UV lasers to perform "cold marking," ensuring that no extra heat stress is applied to materials, including those with high reflectances, such as gold, silver, and copper. Thus it produces less soot and burrs caused by the typical marking process. 3W UV laser marking ensures a high-quality, high-contrast mark in one application. 3W UV laser can generate greater contrast for more appealing aesthetics and improved readability and precision. The 3W UV galvo lasers are as fast as other fiber lasers on the market and significantly faster than their gantry-based counterparts.

3W UV Laser Marking Machine
Product Description
Versatility: 3W UV Laser marking can be used on many products in various industries, including aerospace, automotive, defense DOD, and medical and electronic components.
Maintenance Free: 3W UV laser marking doesn’t require any consumables, no downtime associated with
cleaning or repairs, and the engraving process is quick and simple.
Fast Processing: 3W UV lasers are better absorbed than other wavelengths and marking techniques by virtually
all materials, requiring less power to produce a clear mark in one application with high-quality and high-contrast results.
Low Operation Cost: Compared with other fiber lasers, 3W UV light has a remarkably higher material absorption rate, which ensures one-pass application and low power consumption.
Damage-Free Marking: 3W UV lasers can mark highly reflective materials like gold, silver, and copper with minimal heat damage thanks to the high absorption rate of UV light, which protects the material surface from damage, and enables corrosion-resistant marking.
Quality: UV lasers create easy-to-read marks far superior to printed marks or labels. 3W UV laser ensures crisp, high-contrast permanent marking thanks to the small beam size.
Special Applications: During the laser marking process, the marking device does not come into direct
contact with the product, allowing for clean operation with minimal contamination. 3W UV lasers are perfect for
industries requiring sterile product processing.
