Optical density (OD) ratings:

  • OD 6+ @ 190–400 nm

  • OD 5+ @ 870–1200 nm

  • OD 6+ @ 1000–1100 nm

  • OD 7+ @ 1020–1100 nm

  • OD 6+ 9,000-11,000nm

This window is engineered to reduce the visible brightness of the welder’s arc while providing effective attenuation of the stated laser radiation.

Laser windows can be custom cut, molded, and drilled to your CAD specifications for use in machine housings and industrial enclosures.

All windows are labeled with their optical density and wavelength specifications.

Laser safety eyewear should be worn at all times when lasers are in use. Laser safety windows are not a substitute for other PPE.

All our laser safety equipment meets or exceeds the United States industry standard ANSI Z136.1 and is intended for use with the appropriate laser systems.

Gideon (Fuquay-Varina, US)
lens on the helmet blocks preview / pilot laser...

All handheld laser welders have a preview laser for the welding width and location of the laser while not welding. This lens blocks that laser as well. Without seeing that preview laser it's almost impossible to weld. They should have thought this through before using a lens that blocks basically all laser wavelengths.

Hi Gideon,

Thank you for sharing your experience. We’re sorry the Shade 5 filter didn’t work out for your setup.

Shade 5 is our most protective welding plate—it’s designed to block the intense white-light from the weld arc and a broad range of laser wavelengths. The trade-off is very low visible-light transmission, which can dim or completely block the low-power preview or alignment beams on many handheld welders.

If seeing the alignment beam while you work is critical, Shade 3 offers a better balance between visibility and protection. Just keep in mind that it does let in more light overall, so it provides less protection than Shade 5. Choosing Shade 3 is a matter of accepting that trade-off to maintain a clear view of the aiming beam.

We’d be happy to:

Exchange your Shade 5 plate for a Shade 3 at no cost, or

Refund your purchase in full if you’d prefer to return it.

We’ve also added a note to our product documentation clarifying how each shade affects preview-laser visibility so future buyers can pick the right option from the start.

Please let us know which solution you’d like (or if there’s anything else we can do) and we’ll make it right.

Thank you again for helping us improve.
