    Near field vs far field. I assume the beam is large close by and narrows to focus at distance. If not that's truly amazing. Do it for red! I'd need it to fit 3mm scanners.

    Yes, That's what beam expander are all about, The beam size coming out of the beam expander is 30mm x 30mm square and with the beam expander focused at 50 feet that beam is 6mm x 5mm !

    Or i can focuses the beam so it's stays 32mm x 29mm with a small amount of divergence as the beam travels.....

    I also have a diff output lens assy that only expandes the beam a little bit so the beam size coming out of it is only 12mm x 10mm

    Sorry but you lost me again ?
