Hey guys I was wondering if in Hansolo777's design would it have worked if he put it thru a beam expander. One that had been adjusted to take the incoming light at the same angle as the incoming light from the double convex lens. So that when you flip the beam expander around it would focus it into one beam. Or does a beam expander not work like that? It seems to me I am thinking of optics like Hansolo and that is scaring me I don't want to be someone who doesn't know what they are talking about, yet thinks they are an expert. Which by the way I'm not just a chemistry major who loves lasers.
