This machine sees a maybe 2 hours use a week, and I've had it a few years, and noticed that the existing mirrors needed to be replaced. The new mirrors were easy to install and instantly improved the consistency of cuts. I did a recalibration of the mirror angles prior to use, which doubtless helped, but the machine is working like new again. I can't vouch for the longevity of this product, I just don't know how well they'll stand up. Review: Mirrors were a perfect fit and came packaged very well...foam package, wrapped, and plastic protective cover over the mirrors. Cheap little upgrade over my OEM mirrors. ## Features - Material: Gold-Plated Silicon - Diameter: 25mm/0.98"; Thickness: 3mm/0.12"; Shape: Plane;Transmittance: >99.2% - Made by multiple processes;Superb coating art,Precision slicing polishing and grinding processes,Excellent optical properties,High working efficiency,Long working life. - Good replacement for the K9 mirror for K40 or the other 40W engraver/cutter. - It can be used for CO2 laser low and high power engraving and cutting 40W/50W/80W/100W/130W/150W/200W/300W/400W. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01DP2HT58 | | Brand | CNCOLETECH | | Customer Reviews | 4.5 4.5 out of 5 stars (57) | | Date First Available | 29 September 2017 | | Item Weight | 24 g | | Material | Gold | | Model Number | LM-Si25 | | Package Dimensions | 9.7 x 8.3 x 2.6 cm; 24 g | ## Images ![25mm CO2 Laser Mirror Si Reflective Lens 3PCS CO2 Laser Lens Si Gold Plated Laser Mirrors Dia 25mm Co2 Laser Mirror for CO2 Laser Machine - Image 1](https://m.media-amazon.com/images/I/81pBusBYSpL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by S***L on 21 July 2020* I used these to replace the mirrors on my at-home 100W CNC Lasercutter.
