result shoud be a 5x4mm beam @1mrad, but you will have either get the heights correct
with the two lasers set on the horizontal polarisation or use a wave plate to rotate the beam for the pbs so the beams end up like #
and by the looks of your pics you will have to adjust your setup to use knive over for two of the beams if your not going to use a wave plate
the fiirst micro labs quadkit did not allow for this unless you had the quad kit elite
he is using the quad elite (separate holders) they can be oriented in to a one axis side by side and one axis a knife over (customer provides the right thickness of shim for what ever beam size you are using). For a set up like this "llll" you would need my four banger kit. it appears that the right lens are important here too.
