I'm thinking about making a low divergence add on for my Aries (the same principles can be used for other lasers)

Basically, I would get a "cap" 1.5" in diameter and add an achromatic or plano convex lens to it (flatter side toward the beam source). Hopefully it will make the divergence better. I've just purchased about $100 worth of lenses and mounts from Sunex (http://www.optics-online.com/) and I'll keep you all up to date.
The biggest problem will be centering the mount on my laser so the axis of the beam is parallel to the axis of the lens.
