CNCOLETECH CO2 Laser Lens Dia:15mm FL:2 or 50.8mm Laser Mirror CVD ZnSe Focus Focal Lens for CO2 Laser Engraving Cutting Engraver/Cutter 40W-200W

Better replacement for the boss laser. Working great better than the original one that came with the laser.

Muy bien protegida y embalada, algo muy a tener en cuenta en un producto delicado.

Yeah this is not 12mm and therefore unusable junk.

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

12mm lense is head and shoulders above the one that came in my k40.

I noticed last night that I was starting to get artifacts along the edges of my cuts. Thinking it was a mirror issue, I checked all of those only to find they were all fine. When I inspected my focal lens that is less that has been on the machine less than 1 month and used only a few times. I found that the lens itself was the issue and split in two pieces. For the cost, I certainly would have expected an item that would last more than 30 days. Needless to say the return period expired yesterday and now I am stuck finding a new focal lens somewhere else.

Works

Not a good discription

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