Combining multiple HeNe beams?
Over the weekend I became the lucky owner of several FREE, old, but working, Melles Griot HeNe 632nm 5mw laser heads and power supplies. I'm thinking about incorporating these into an inexpensive "beam box" as a backup to my RGB projecter I'm getting ready to construct.
Could anyone recommend the optics that would be required to combine the outputs from 4 of these lasers into a single beam? I'm looking for the cheapest workable solution, since the RGB projector is pretty much sucking dry the hobby fund!!
Thanks!
