Glass Laser Marking: Precise and Permanent Marking Techniques on Transparent Surfaces
Glass laser marking is a high-precision technology used to create permanent marks on transparent and fragile surfaces. Since glass materials respond differently to the laser beam, choosing the correct laser type and parameters is of great importance. CO₂ laser and UV laser systems are widely used in glass marking applications. This guide explains in detail laser marking techniques on glass surfaces, methods for reducing the risk of cracking, and examples of industrial applications.
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 by creating microcracks on glass surfaces.
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 use 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.
Contrast creation
On glass surfaces, contrast is generally achieved through frosting.
QR code and DataMatrix
2D code marking can be applied on glass surfaces with laser.
Industrial application areas
- Glass packaging
- Laboratory glassware
- Optical components
- Medical glass products
