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

Ottimo acquisto

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 great

Would have given it 5 stars but it filters out red laser pointer, other than that it seems to be doing ok.

Identical to the name brand one for my laser, at a fraction of the cost.

Yeah this is not 12mm and therefore unusable junk.

Bought this to replace my damaged 2 OEM lens for my Thunder Laser. I did a ramp/focus test using LightBurn and found my new lens to be focused tightest at 5.5mm (vs. the nominal 6mm the machine is set up for). I run it at 5.5mm for precise work, but put it 1mm out of focus at 6.5mm when I sometimes want a wider beam for engraving. Overall, it seems to work well.

Great value for a good quality lens. Focus was clean on install. Coating is more substantial than other inexpensive lenses that I’ve tried. We’ll see how it’s going in a few months.

Die Linse wird in einer Wärmebildkamera verwendet.

Helps to focus
