I don't know everything about anything, but I enjoy learning as much about most everything that I can.
It would be better to correct each beam individually but you could try to do it in rows..... however it's the short side of the beams spot that becomes very wide over just a few meters.
So in the case of the nubm35 which has 2 rows of 7 you would need 7 prism pairs, nubm37 either 4 or 6 depending on the layout, but misalignment will become an issue.
You see what starts as a tall vertical rectangle becomes a wider horizontal rectangle, so you have 2 bundles from the 2 rows of 7 that sort of overlap ( nubm35 ), but with distance, just a few meters, the spread ( width ) of the bundles also expands. The factory alignment looks good up close, but with any real distance you see it's far from perfect.
You really need to build your own array from individual diodes and use a cylindrical pair to correct each beam, then knife edge all the beams and finally run those beam bundles through a big beam expander.
I played with multiple beam concepts a while back here >
Multiple Beams
Anyway you can get a nubm35 and safely test it and see what I am talking about, it's pretty neat they do as well as they do using a tiny reflector to align each beam inside the array.
This is from 8 inches away to 8 feet away and the length of the bars continue to grow as does the misalignment of the bars with distance.
You could knife edge each string of 7 from several arrays into a bundle aligned to infinity and run that bundle through a big beam expander, or try to correct by way of the prism pairs, also you can easily remove the gang lens and replace it with one of your own gang lenses or lens arrays with lenses of a different focal length to aid in correcting the beams as per having space to work, the substrate stacks are sealed behind an AR coated window, the gang lens is only held in place with a couple beads of glue over top of the arrays window.
Although improvement is possible, these will never be able to produce a 1 inch spot @ 1000 meters, but they could be bundled and improved a little to make for more fun a little further out. ** Always Remember Safety 1st **
Note: nubm35's are the better deal and can be had for less $$$ per unit, also could be easier to work with.
