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

I used these to replace the mirrors on my at-home 100W CNC Lasercutter. 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.

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.

Buen producto, para mejorar, se pela el color amarillo, pero queda color natural y sigue funcionando

First one (of 3) i opened had significant scratches and a line across it. The line likely won’t effect the laser since it is towards the edge. Second one not nearly as bad. I needed them ASAP so will not be returning them but totally disappointed in the quality.

Work Great
