Laser Safety Window – 407 Acrylic Sheet | OD 5+ @ 190–375 & 10,000–11,000 nm
received quick and was very happy with the product
The ship internationally to Mexico.
I put the exact dimensions for a Laser Safety Window Covering in the same order as the website has them, width first and then height. I received the "Warning" notices stitched on sideways. I recommend stitching on sleeves with an opening so that the customer can correct the "Warning" orientation if they are made incorrectly/sideways. Overall though, the dimensions fit perfectly and the magnets are strong enough to hold them up.
Thank you for your feedback — and we’re sorry to hear the warning label arrived oriented incorrectly. We understand how frustrating that can be, especially when you followed the width x height format as listed on our site.
While most of our laser window coverings are larger (making orientation more apparent), we recognize that in more compact configurations, it can be less intuitive. For any future orders, you're always welcome to submit a photo or drawing if you’d like the warning label placed in a specific position — we’re happy to accommodate.
We want to make this right. Our team is reaching out to you privately and would be happy to send a corrected version so it’s to your satisfaction.
We do appreciate your note that the fit was perfect and that the magnetic mounting is working well — and we truly value your feedback as it helps us continue to improve.

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.
