AI Overview
UV laser engraving produces precise, smooth, high-contrast, and permanently frosted, white marks on glass, often without needing masks or sprays, by utilizing "cold processing". These lasers (commonly 355 nm) directly break molecular bonds without causing heat stress or shattering, offering a high-precision alternative to sanding, with superior results to CO2 laser etching.
UV Laser Glass Engraving Key Features
- High Precision: Creates detailed logos, bar codes, and delicate designs on various glass types, including quartz.
- Smooth Finish: Produces a frosted white look that is smoother to the touch than the micro-fractures often left by CO2 lasers.
- Minimal Preparation: Unlike diode lasers that require masking, UV lasers can often engrave directly on the glass surface.
- "Cold" Processing: UV lasers (like the ComMarker Omni 1) use a 355 nm wavelength to avoid heat stress and cracking.
Process Overview
- Preparation: Clean the glass surface thoroughly. While coatings aren't usually necessary for UV, cleaning is essential.
- Software Setup: Design the image or text.
- Engraving: The UV laser marks the surface by interacting with the material at high speed.
- Post-Processing: Clean off any minimal residue with a soft cloth or water.
UV vs. Other Laser Types for Glass
- UV Laser: Superior precision, smooth frosting, no cracking, high expense, specialized for high-quality, fine marking.
- CO2 Laser: Good for thick glass, causes small fractures for a, sometimes, rougher frost, high heat, and lower cost.
- Diode Laser: Requires masks (paint, tape) to create a white, frosted effect, lower power, lower cost.
