I really expected it to melt right away but it has done well at full power and 90% duty for quite a few cuts already - no noticeable issues yet! I was quoted almost $400 for a "legit" replacement, so like $25 seems too good to be true! ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Use with my thermal camera *by B***N on Reviewed in the United States on June 16, 2023* Works great with my thermal camera for identifying possibly shorted smds. I 3d printed a mount found on thingiverse ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Very Surprised on how well this performed. *by R***H on Reviewed in the United States on May 30, 2023* This lens is fantastic. I've been using much more expensive lenses in my laser cutter but no more. This lens out cuts and out engraves the pricier ones. Honestly, when I first got it I wasn't too impressed. Although it was very well packaged, the lens appeared to be a little cloudy and I really didn't expect much out of it. However, once I got it in my machine it performed better than I ever would have imagined. I won't be going back to my old lenses. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.cy/products/41665472-19mm-co2-laser-lens-laser-mirror-pvd-znse-focus-lens](https://www.desertcart.com.cy/products/41665472-19mm-co2-laser-lens-laser-mirror-pvd-znse-focus-lens) --- *Product available on Desertcart Cyprus* *Store origin: CY* *Last updated: 2026-04-22*
