APC CO2 Laser Nozzle and Lens Tube 4-pc Kit for 18mm Dia Lens Uses PN-16.1550-KIT4-RLA | 38.1, 50.8, 63.5, 101.6 Tubes, Nozzles, Alignment Tool Suitable for OMTech MF2028-60 USB570a

I've wanted to make this purchase for over a year now but they're a little pricy, so I held off but now that I have them, I AM IN LOOOVE and wish I'd have bought them sooner!! The only thing I wasn't super pleased with was the alignment tool as I couldn't get it to work quite right, and it was just easier to do the alignment the regular, tedious way but other than that (and even that I'm sure was on my part as I'm not as knowledgeable with my laser as I could be if I spent more time learning it's ins and outs). I also purchased their 3pc mirror kit and installed all of them. It took me a day to realign my laser after installing the new mirrors, which was expected, but now (with the new mirrors and the new lenses) I can cut 1/2" MDF at a lower power than I could originally cut 1/4" MDF in the past!! I tried and tried to cut 1/2" MDF before purchasing these and there was absolutely NO WAY (even at 75% power and 4 passes my machine wouldn't cut it - I'm sure I had alignment issues as well though) but now that I have the new mirrors and lenses, I can cut the 1/2" in two passes at 48% power @ 5 speed. Before I needed 65% power @ 10 speed to cut 1/4" MDF and now I can cut that at 30% power! All of my settings for my other materials have changed for the better as well. The time alone that these purchases are going to save me is WAY worth the money spent!! I'm sure my alignment could still be better but for now it's the best I can get it.

Good lens set. I used them on my 130W Omtech CO2.

Exactly what i needed for my Omtech, shipping estimate was over a week but I got it in two days!!!
