19mm CO2 Laser Lens, Laser Mirror PVD ZnSe Focus Lens 50.8mm / 2" Focal for CO2 Laser Engraver Cutting Cutter

I used this 19mm ZrSe lens in an Epilog Fusion M2 120W CO2 laser. I really expected it to melt right away but it has done well at full power and 90% duty for quite a few cuts already - no noticeable issues yet! I was quoted almost $400 for a "legit" replacement, so like $25 seems too good to be true!

Works great with my thermal camera for identifying possibly shorted smds. I 3d printed a mount found on thingiverse

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.

Tal como lo indica la descripción

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.

Works great and packaged great

Have a boss laser and it has a couple cloudy spots on the lens. While it still cuts ok, wanted a backup that did not cost me $220. When I got the new lens in, it was well wrapped and packaged. Gave it a quick clean, installed it and it cut like a champ.

Great
