Why Protected Windows Extend Your Laser’s Life

Protected windows act as a sacrificial barrier, stopping contaminants before they reach expensive optics.

They reduce unplanned downtime and keep power delivery consistent across shifts.

Lower maintenance cost and longer lens life by blocking debris and back-spatter.

Stable cut quality thanks to cleaner optical paths and fewer re-alignments.

Inspect daily under soft, angled light. Replace at the first sign of pits or iridescent stains.

Use lint-free swabs and approved solvents; avoid circular rubbing that can trap grit.

Always handle protected windows with clean gloves to prevent oil contamination.

Ensure the window is seated flat and sealed properly to avoid leaks and dust ingress.

If cut quality declines, inspect for microscopic scratches or coating damage that may scatter the beam.

Persistent fogging usually indicates excessive moisture in assist gas or an air leak in the optical path.
