Multiple beams after passing through dichro - is this normal?
FINALLY, after upteen-gazzillion delays and excuses, I've started active assembly on my RGB projector (no, seriously, Buffo!). I can already tell the optical alignment process in going to be TONS of fun! 
SO, here's the noob question:
I'm using a dual-Maxyz for my red laser. Through a little tweaking of the mirror & PBS mounts on the dual plate assembly, I'm able to get a pretty nice single spot on my flame retardent (
) target . However, I noticed that when the beam is reflected off of a pass green / reflect red dichroic filter (Edmunds), I wind up with one normal-size beam spot, and a couple of smaller beam spots touching either side of the primary beam.
Is this normal for a beam that first passed through a PBS cube? 
Thanks in advance!
