Two lasers in one system: flexible glass processing with the LiSEC LSP-A

HOW DOES THE COMBINATION OF ENGRAVING AND DECOATING WORK?

The LSP-A integrates two different laser sources into one system, creating a flexible solution for glass processing. The approach: surface structuring and selective coating removal are carried out in a continuous process—without additives or consumables.

CO₂ LASER FOR STRUCTURE AND VISIBILITY

The first process is based on a CO₂ laser acting directly on the glass surface. Depending on the settings, minimal material removal creates matte or engraved structures with clearly visible contrasts.

Typical applications:

• Bird protection glass: Dot-shaped structures in a defined grid pattern make glass surfaces visible to birds and reduce collisions
• Decorative glass: Logos, lettering, or designs can be applied directly to the glass
• Slip-resistant surfaces: Dense structures enable certified slip resistance (e.g. R9 and R10)

NIR LASER FOR PRECISE COATING REMOVAL

WHAT DISTINGUISHES THE LSP-A IN OPERATION?

The second laser source—a near-infrared (NIR) laser—is used for the selective removal of functional coatings without affecting the glass itself.

This opens up possibilities that are difficult to achieve using mechanical processes:

• Finest structures: Grids with widths of only around 20 µm

• Retention of function: As only a small portion of the coating is removed, its functionality is preserved
  

New applications:

• Transmission for mobile communication signals

• Preparation for heated glass

• Precise mirror decoating without matting the glass

WHAT DISTINGUISHES THE LSP-A IN OPERATION?

A key advantage lies in the combination of both processes in one system—enhanced by high efficiency and flexibility.

Key highlights at a glance:

• Combination of engraving and decoating in one system

• Processing without additives or consumables

• High productivity, e.g. up to 55–60 m²/h for bird protection glass

• Two CO₂ lasers operating simultaneously for parallel processing

• Flexible integration—possible before or after tempering

• Use as a standalone machine or fully automated in lines (e.g. as a bypass)

• Laser safety class 1—no additional protective measures required

• Energy-efficient design

Thanks to these characteristics, the LSP-A can be used in a wide range of production environments—from façade construction to interior applications such as design glass or functional mirrors.

AVAILABILITY AND FURTHER INFORMATION

From 20–23 October 2026, you can see the LSP-A live at the LiSEC booth, Hall 17 / A64 in Düsseldorf.

The LSP-A can be flexibly integrated into existing production lines or used as a stand-alone solution. Further information and personal consultation: 👉 https://www.lisec.com/about-lisec/contact

Summary 

The combination of two laser processes in one system significantly expands the possibilities of glass processing. The LSP-A enables both functional and design applications—efficiently, flexibly, and without additional materials.
