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

Good

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

This lense is so much better than the stock k40 and the difference was exceptional

Works great with BOSS lasers.

Not a good discription

I noticed last night that I was starting to get artifacts along the edges of my cuts. Thinking it was a mirror issue, I checked all of those only to find they were all fine. When I inspected my focal lens that is less that has been on the machine less than 1 month and used only a few times. I found that the lens itself was the issue and split in two pieces. For the cost, I certainly would have expected an item that would last more than 30 days. Needless to say the return period expired yesterday and now I am stuck finding a new focal lens somewhere else.

works great

Confezionamento top. Lenti OK!!!

Would definitely buy again!

Das wechseln der Linse ergibt ein weit besser Ergebnis. Die Linse muß richtig eingebaut werden und nicht mit den Fingern berühren. Beim Kauf auf den richtige Durchmesser achten.
