Review: Incredible - 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 Review: Works well - 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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01D1QHQUQ | | Brand | JtechPhotonics | | Customer Reviews | 4.6 out of 5 stars 67 Reviews | | Item Dimensions L x W | 29.5L x 30.2W centimetres | | Item Weight | 12 Ounces | | Item weight | 12 Ounces | | Manufacturer | JtechPhotonics | | Material | Acrylic | | Operation Mode | Automatic | | Operation mode | Automatic | | Part Number | Shielding_445nm | | Product dimensions | 29.5L x 30.2W centimetres | | Style | Laser | ## Product Details - **Brand:** JtechPhotonics - **Material:** Acrylic - **Product dimensions:** 29.5L x 30.2W centimetres - **Style:** Laser - **Item weight:** 12 Ounces ## Images ![250nm to 520nm Laser Shielding - 12" x 12" (~30.5 x ~30.5 cm) - Image 1](https://m.media-amazon.com/images/I/31GJE6Ma8VL.jpg) ![250nm to 520nm Laser Shielding - 12" x 12" (~30.5 x ~30.5 cm) - Image 2](https://m.media-amazon.com/images/I/413ywppI0zL.jpg) ![250nm to 520nm Laser Shielding - 12" x 12" (~30.5 x ~30.5 cm) - Image 3](https://m.media-amazon.com/images/I/5137PdhTwkL.jpg) ![250nm to 520nm Laser Shielding - 12" x 12" (~30.5 x ~30.5 cm) - Image 4](https://m.media-amazon.com/images/I/51VlSz70nAL.jpg) ![250nm to 520nm Laser Shielding - 12" x 12" (~30.5 x ~30.5 cm) - Image 5](https://m.media-amazon.com/images/I/41kcjxMtQRL.jpg) ## Questions & Answers **Q: How it is possible to see the cca 5500 mW laser beem through the screen with OD 6+???** A: You can not see the 'beam', but you can see the contact point of the laser on the object you're cutting/engraving. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Incredible *by L***N on 8 June 2023* 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 ### ⭐⭐⭐⭐⭐ Works well *by G***G on 10 September 2021* 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. ### ⭐⭐⭐⭐ Verified laser protection *by S***H on 17 May 2024* 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. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/170322217-250nm-to-520nm-laser-shielding-12-x-12-30-5](https://www.desertcart.tn/products/170322217-250nm-to-520nm-laser-shielding-12-x-12-30-5) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-25*
