Chinese 100W laser from Orion Motor. Cut fine for a while but one day it cut very poorly. I'm now on my 4th lens, they all cut fine for a few hours, then, BAM!! Looks like they get a little cloudy and then start absorbing the laser. One had a small hole cut all the way through it. Two darker ones are original and one laser people sent as a replacement. The lighter 3rd was one I bought off Amazon. I think previous two were 1.5" focus, I bought a 2".
ANY help would be GREATLY appreciated!!
