Works well!
I purchased this as an add on to my 60w fiber laser. It works perfectly. I believe it works better than the stock lenses I have.

Shipped fast, really amplifies the laser power!
Installed this on a 50W Galvo that originally had 150mm lenses. The power from this is so much more I can engrave coins at 1/2 the time at the cost of a smaller build area. A must have in the laser accessories kit to make the most of your engraver.
