I will then swap out the diodes for the Oclaros and retest to show what if any improvement occurs.
that's what i wanted to hear
I can assure you that what you have deducted for simon's quad is correct. The "garbage" around the beam is there. The wings are prominent, too, no magic involved. The scanner mirrors will clip that to some extend. The limit of this setup is around 1mrad, maybe a tiny bit lower, with very tedious and careful setup. I know what I am talking about, I have one and have worked on it with detailed instructions from simon (and lots of pictures back and forth via email).
Besides, Simon never claimed to have made the ultimate quad setup. He claimed to have made a very small footprint and stable design, which produces a very decent result, with no drift and things dropping out of alignment. I know this to be true, because I did it and it works
So, I am more than eager to test simon's quad with planters idea of the last cylinder - PCX setup (I just don't have any pcx lenses, nor have the laser-budget at the moment)
The only sigificant difference I see is eric using the 4mm lens which is more forgiving in terms of centering and of lower initial divergence, while simon's quad is built around the 2mm lens which is a small pita to get dead center and attention to detail makes a whole world of difference.
