This is the same technique (in reverse) that professional video cameras have used for decades to feed color separated CCDs. So, should Sony sue Arctos? Many medical lasers use dichroic filters to overlay aiming lasers onto the therapeutic laser to target a treatment site. Two wrongs don't make it right
