  • Arrived quickly
Size: 110x110mm
Seller responded quickly and new lens arrived in a few day when i needed it. Lens description was spot on and worked well on machine

  • Shipped fast, really amplifies the laser power!
Size: 70x70mm
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.
