250nm to 520nm Laser Shielding - 12" x 12" (~30.5 x ~30.5 cm)

The media could not be loaded. Absolutely incredible, it takes out all reflective or radiant blue light, you just see the beam 😀. I can't believe it no more soar eye's. Will get more

It took a while to get this, but that was issues with the post. Customer support from the supplier sent me a replacement screen when the first was lost in the shipping. Now that I have fitted, i can see the laser working in the enclosure I made for it. Would recommend it.

Seems very overpriced for a small bit of plastic, but to have the laser protection tested and verified is probably worth the cost. I'm using this as a protection window as an additional safety layer for my laser cutter. I have a 445nm laser engraved as this does reduce the lasers brightness. Helps cover those areas that my safety glasses don't cover.

Manufactured by J Tech Photonics a well known and reputable manufacture of Laser Shielding and laser mounts. Furthermore this is perfect for the Sainsmart 5.5w 445nm blue laser, and are unable to see the laser beam through the shielding. Furthermore the size is plenty to either cut to make a custom surround or I plan to build a new enclosure with the whole sheet as a window.

Used this when making an enclosure for my 3018 CNC/laser machine.Don't have the equipment to scientifically test how well this performs; but it seems to do what it should; the 400nm-ish laser is much dimmer and a drastically different colour when viewed through this!

Just what I needed as building box to keep laser in. Great viewing window when checking progress

Pricey but does a good job..

Good product and seller was very helpful
