These mirrors when I replaced them in my K 40 made the absolute world of a difference, especially since my mirrors were torched well pass what they should be.The highest quality, laser cut of mirrors. I’ve used myself, absolutely fit perfect, and honestly worth every penny if you knew how much you can make off of having your better mirrors put in. They work amazingly, and they are great options for upgrading your cutters ### ⭐⭐⭐⭐⭐ Love them! *by on Reviewed in the United States March 24, 2026* SO much better than the stock mirrors. I was able to lower my power and raise my speed and get a way better cut. I will be ordering a backup set, for sure! ### ⭐⭐⭐⭐⭐ Good quality *by on Reviewed in the United States December 23, 2024* Used these mirrors to replace the mirrors in my CO2 laser worked well no problems. I will buy them again when needed. ## Frequently Bought Together - Cloudray Laser Si Reflective Lens Gold Plated Mirror 25mm for CO2 Laser Engraving & Cutting, 3PCS - Cloudray CO2 Laser Lens 18mm Laser Mirror CO2 Laser Focal Lens CO2 Focus Lens,PVD ZnSe for CO2 Laser Engraving Cutting Machine,Laser Cutter 30W-100W,Dia 18mm FL50.8mm - Cloudray CO2 Laser Lens 20mm Laser Mirror CO2 Laser Focal Lens CO2 Focus Lens,CVD ZnSe for CO2 Laser Engraving Cutting Machine,Laser Cutter 40W-200W,Dia 20mm FL50.8mm --- ## 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.us/products/75095997-cloudray-3-pcs-laser-si-reflective-lens-gold-mirror-25mm](https://www.desertcart.us/products/75095997-cloudray-3-pcs-laser-si-reflective-lens-gold-mirror-25mm) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-25*
