UV Laser Marking Machine: Working Principles
The UV laser marking machine operates on photochemical interactions:
- Laser Generation: A 355nm UV laser emits short-wavelength beams (photon energy: ~3.5eV), focused into micrometer-scale spots (10–15μm diameter) via optical systems.
- Material Interaction: High-energy UV light directly breaks molecular bonds (vs. thermal ablation), vaporizing surface molecules to create permanent marks.
- Cold Processing Advantage: Unlike traditional lasers (thermal effects), UV lasers generate ≤5μm heat-affected zones, avoiding material deformation or discoloration.
UV Laser Marking Machine: Technical Features
