18mm CO2 Laser Lens, Laser Mirror PVD ZnSe Focus Lens 63.5mm / 2.5" Focal for CO2 10600nm 10.6um Laser Engraver Cutting Cutter

I've been buying inexpensive lenses for my CO2 laser on Amazon for a couple of years now and have never had a problem with them. I've tried lenses that cost twice as much and saw absolutely no difference in performance. I consider lenses to be a consumable and thus the less expensive the better and these work well.

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.

Why did you pick this product vs others?: The item met the specifications I needed.

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.

Good

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

This did the trick when I broke my original lens for my P2 and didn't want to pay the extra money for one from Xtool. Put the lens in and it's been working just fine ever since! I will buy from them again if I have to, but I really don't want to break another one! LOL! It came packaged VERY well!!

Excelente producto, lent de calidad, cumple con las especificaciones

Great

One year review and I must say that I'm very happy with this item. It has made a difference in the quality of the engraving and cutting of the wood items that I make for inlays, and after one year it is still going strong, as I'm not sure what the life expedience is for them. So for me it was well worth the investment for my K40

Excelente producto y de calidad era lo que esperaba.

Muy buen producto
