Thanks for the tests. Interesting convergance issues. Maybe it is best to simplify and start measuring slowly. I have convergence issues only at about 10feet when doing 9x squeeze using two 3x concave lenses.
Lets maybe set the distance at 10m and see exactly what best you can get projected at that distance. Maybe take a photo against yellow paper of flat gray surface with ruler.
All these 2x, 3x, 4x, and 6x square or rectangular lenses we use to shrink the beam and put right in front of the G2 lens are concave. Convex is on the end. Not sure what you mean.
Could you give some measurements in millimeters. Its really hard to keep the track with all the fractions :-( Also, what is the beam output diameter? What power output are you using?
Burn marks are not best way to measure as the center is always the hottest.
