Yes — laser safety windows can be integrated into laser safety curtain systems to provide visibility into the laser process while maintaining containment.
This is commonly done in laser welding areas, industrial laser rooms, automation environments, and other applications where operators need to monitor the process without opening the containment system.
Unlike laser barriers or rigid wall systems, laser safety curtains are flexible materials that may need to roll, fold, or retract during normal operation or storage. Because laser safety windows are rigid materials, this creates additional design considerations.
How Are Windows Integrated Into Laser Safety Curtains?
Laser safety windows are typically installed as removable modular inserts within the curtain system.
This allows the window section to be removed if the curtain needs to be rolled up, folded, transported, or stored. Removing the rigid viewing window helps prevent cracking or mechanical stress during handling.
If the viewing window is removed, a protective flap can cover the opening area to maintain continuous containment coverage.
Why Add a Viewing Window to a Laser Curtain?
Integrated viewing windows allow operators to monitor the laser process while the curtain system remains closed.
This can help reduce unnecessary curtain access while improving visibility into:
handheld laser welding operations,
robotic laser systems,
laser processing cells,
automation equipment,
and other enclosed laser work areas.
Important Considerations
The viewing window must still be selected appropriately for the laser hazard and application.
Important considerations include:
wavelength compatibility,
optical density (OD),
visible light transmission (VLT),
maximum irradiance exposure,
reflections,
curtain movement and handling,
and overall containment design.
Laser curtain systems and viewing windows should be reviewed by a qualified Laser Safety Officer (LSO) or other knowledgeable laser safety professional to help ensure the configuration is appropriate for the application and complies with applicable standards including ANSI Z136 where applicable.
