Glass Laser Marking: Precise and Permanent Marking Techniques on Transparent Surfaces
Glass laser marking is a high-precision technology used to create permanent markings on transparent and fragile surfaces. Since glass materials respond differently to laser beams, choosing the correct laser type and parameters is of great importance. CO₂ laser and UV laser systems are commonly used in glass marking applications. This guide explains glass surface laser marking techniques, methods for reducing the risk of cracking, and examples of industrial applications in detail.
Glass Laser Marking Technology
Why is glass marked with laser?
Glass surfaces require permanent marking because they are resistant to chemical and physical effects. Laser marking meets this need.
Use of CO₂ laser
CO₂ laser systems perform marking on glass surfaces by creating microcracks.
Use of UV laser
UV laser systems provide more precise and controlled marking.
Surface interaction
The laser beam creates microstructural changes on the glass surface.
Risk of cracking
Incorrect parameter usage may cause cracking on the glass surface.
Heat control
Controlling the heat effect is critically important in glass marking.
Marking precision
UV laser systems are suitable for micro marking.
Creating contrast
On glass surfaces, contrast is generally achieved through frosting.
QR code and DataMatrix
2D code marking can be performed on glass surfaces with laser.
Industrial application areas
- Glass packaging
- Laboratory glassware
- Optical components
- Medical glass products
