Really quite superb
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!

Awesome
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

Leistung und Laserbrennpunkt ist besser.
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.
