Protective glass for laser machines

Protective Windows for Laser Machines

Protective windows are critical components in laser machines, designed to shield internal optics such as lenses and mirrors from contamination and thermal stress. By preventing dust, debris, and process residue from entering the beam path, protective windows help maintain laser performance and extend the lifespan of optical components.

We supply high-quality protective windows for both CO₂ and fiber lasers, tailored for different wavelengths, power levels, and machine types.

Supported Machine Brands

We offer compatible protective windows and spare parts for many of the world’s leading brands in laser cutting and welding, including:

When to Check the Protective Window

If you notice reduced cutting performance, inconsistent beam quality, or increased reflection, the protective window is often one of the first components to inspect. Dirt, spatter, or thermal damage can have a major impact on processing quality and should be addressed promptly.

Support & Troubleshooting

We offer free diagnostic support for our customers. If you’re experiencing issues with cutting or welding, we can help determine whether the root cause lies in the protective window or elsewhere in the system.

With extensive experience and the necessary testing equipment, our team can analyze, diagnose, and recommend the correct replacement – quickly and accurately.
