FAQs

Got questions? We’ve got answer...

How often should I replace a protective window?

Depends on your cutting environment and power — check regularly for signs of residue build-up or surface damage.

What if the AR coating gets scratched?

Scratches can increase reflection and loss — replace the window if the surface integrity is compromised.

Can I use these on any laser brand?

Yes — as long as you select the correct diameter and thickness for your head model.

What happens if I don’t use a protective window?

Back-spatter and debris can directly hit internal lenses, significantly raising replacement costs and downtime.

Are these original OEM parts?

No. Machinist’s Vault protective windows are OEM-compatible replacements, not original manufacturer parts.
They are engineered to meet or exceed OEM performance specifications.
