18mm diameter lens tube with ZnSe focus lens or 3pc kit +Alignment Tool

Nice, very nice

I ordered the 18mm tube+lens kit with the alignment tool. So for I've only used the 1.5" lens and boy does it do a nice job on engraving. I've got really great work on poplar. Slate, well, I'm still trying to find the right speed/power ratio for doing detailed 3D illusion work, but for just straight patterns, great stuff. I do wish that APO sold a red-dot combiner assembly for the Chinese lasers, particular the Monport 80W. Having to realign the damnable red-dot pointer each time I change a lens is a royal pain in the backside. Do love the fact that all the lenses focus at 10mm. Now, all I have to do is figure out how to set/reset the autofocus so that it focuses at 10mm.
