On the machines I used to operate, on the top side of the lens, it had a ring/washer made out of resin core solder to give room to expand if it got hot. Could possibly use a thin viton Oring to do the same job. On these machines, they also had a small air bleed onto all mirrors as well as the lens.
Finally getting some time to get caught up a bit. I'm looking forward to seeing more about the adjustable bed height. I know I can't cut much thicker stuff, but some of the parts I want to engrave....or etch into the anodizing.....are a good bit thicker....2" or so...? There's not enough room under the lens assembly in it's current configuration.
The laser lens should never be handled with bare skin. They are TOXIC! The broken lens should be handled with even greater care, as to not get any shards into your skin or inhale any of the dust.
There are a few places where you can get drop in laser tubes for these machines, Cloudray being the big one. You can get pretty much everything you need to do any kind of repair or upgrade to them.
you are a master and a great big help thank you my friend

Concave up right? Flat down....
It's convex not concave ... I always remember the difference because, 'caves' go in ...
