So we were having some problems with the Tweezers but they seemed to have been ironed out now. One of the issues was the size of the laser in the back aperture. We ordered some new lenses (thanks Olympus) and that should fix the size issue. Also we were having some resolution issues but it seems there was some burnt dirt on the lens and I think that fixed the resolution as we are getting some nice resolution now. The laser looks nice too (except for having 2 reflections).
