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

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

Would definitely buy again!

Would have given it 5 stars but it filters out red laser pointer, other than that it seems to be doing ok.

Ottimo acquisto

Great value for a good quality lens. Focus was clean on install. Coating is more substantial than other inexpensive lenses that I’ve tried. We’ll see how it’s going in a few months.

Better replacement for the boss laser. Working great better than the original one that came with the laser.

Yeah this is not 12mm and therefore unusable junk.

Confezionamento top. Lenti OK!!!

Quality product. Far superior to lens supplied with K40. Certainly made a vast improvement on cutting and reducing burn.
