25mm CO2 Laser Lens, ZnSe Focus Lens 63.5mm/2.5" Focal, 10600nm 10.6um Laser Engraver/Cutter

Great price , works perfect with my Epilog

No difference from the stock lens and a great price.

Very fast shipping. Works great on my 180 watt laser.

buena calidad

This lens is fantastic. I've been using much more expensive lenses in my laser cutter but no more. This lens out cuts and out engraves the pricier ones. Honestly, when I first got it I wasn't too impressed. Although it was very well packaged, the lens appeared to be a little cloudy and I really didn't expect much out of it. However, once I got it in my machine it performed better than I ever would have imagined. I won't be going back to my old lenses.

Works as advertised

Great fit for the 50w Chinese laser. Mid focal point great for engraving.

I bought the air assist that allows use of 18mm lens, so I gave this lens a shot, the price is decent and the spec. Looked not much different than the more expensive brands.Got it today with also the mirrors from The same sellers. So I installed it in my K40 laser engraver replacing the stock laser head with the new LO head with air assist with the new lens and mirror. InScrewed up the alignment at first, but after making some adjustment and set power to 10% and test it on a cardboard. BAM! It cut thru the cardboard in one pass while before it only leaves a line!Who knows, maybe the alignment was off before, but I definitely think the lens made a difference, for the quality of the coating on both the lens and mirror are better than the stock. It is a worthy upgrade, now marking on stainless turns out great, really helps serve the purpose of getting the K40 in the first place.
