CNCOLETECH CO2 Laser Lens Dia:15mm FL:2 or 50.8mm Laser Mirror CVD ZnSe Focus Focal Lens for CO2 Laser Engraving Cutting Engraver/Cutter 40W-200W

Not a good discription

Would definitely buy again!

Tutto OK, Amazon sempre una garanzia

Good

smaller than others I have ordered but still worked

Replaced original lens in 40w laser cutter and was able to use less power to cut through wood.

Die Linse wird in einer Wärmebildkamera verwendet.

12mm lense is head and shoulders above the one that came in my k40.

Helps to focus

Seriously great buy! I was paying a pretty ridiculous price for the same exact product until I found these! You will not be disappointed!! I’ve bought several and all have been A+
