I have asked this before and really never got an informative answer on how it would or would not work...CAN A BEAM EXPANDER BE USED IN REVERSE TO SHRINK AND TIGHTEN A GROUP OF MULTIPLE BEAMS TO A COMMON FOCAL POINT THAT IS ADJUSTABLE OR CAN THESE BEAMS JUST PASS THROUGH A SINGLE LARGE LENS ONCE, GET A FOACAL POINT AT CLOSE RANGE AND THATS IS? My goal is not to try and get just one beam but extremly compressed beams very close together that is adjustable in it's focal point.
