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

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.

Yeah this is not 12mm and therefore unusable junk.

Very well packed. Outside plastic bag, then a box with foam, then a smaller plastic bag on the box and then the lens wrapped in tissue

Identical to the name brand one for my laser, at a fraction of the cost.

smaller than others I have ordered but still worked

I had red reviews about the dimensions being off. Mine was dead on, as checked by my digital calipers.

Not a good discription

Good

These were the perfect upgrade to my stock K40 co2 laser. Received the product when stated by seller and in the condition it was advertised. Will buy from again.
