MCWlaser CVD II-VI Znse Laser Focus Lens for CO2 10600nm Laser Engraver Cutter Dia:12mm FL: 50.8mm 2"

These have become my lens of choice for my fleet of 12 CO2 laser engravers. I don't think you can do any better for the money! Remember to put them in the correct orientation! :) Highly recommended!

Transformed my k40, stock lens was cloudy and brittle (few places chipped) creating a half moon when fired. This little gem sorted that and have me the power the machine should produce. Thank you

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

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

Excellent. Huge difference between my stock lens and this one.

k40 lasted 2 hours crap

Massive upgrade on the stock lens I had on my K40

Really good packaging lens quality is very good I have much better results following the figment of this.

Works as expected

Ottimo

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.

todo va bien
