CO2 laser cutting of glass
Edges so strong and clean you can skip grinding and washing — contactless thermal cutting for glass from 100 µm up to 3 mm.

Contactless thermal cutting: a focused beam heats the glass, a cold jet follows — a perfectly controlled crack does the rest.
Straight X-Y cutting
For thin glass from 100 µm up to 3 mm — exactly where edge strength matters most.
No micro-cracks, no chipping
The thermal crack runs through the glass without touching it.
Zero post-processing
No grinding, no polishing, no washing — the cut edge is the finished edge.
Cleanroom-ready
No dust, no water, no particles — and no material lost in the kerf.

Cutting with extremely high edge strength
Splinter-free and highest edge quality: the result is a high-quality cut in terms of edge quality and strength. Unlike mechanical scribing with cutting wheels, the laser scribing method does not require any further processing steps such as grinding or washing.
Advantages:
- Maximum yield with minimum scrap
- Thin glass (from 100µm) with high yields
- Precise and clean cut edge with highest edge strength (break resistance)
- Optical glass edge quality
- No micro cracks or chipping
- No material loss during or after the cutting process
- No glass dust particles, therefore suitable for clean room conditions
How it works
A focused laser beam selectively heats the glass — followed by a jet of cold air or an air-liquid mixture. This thermally generated stress results in precise cracking of the glass.
