    Question Can you add blue into the stream without a dichro maybe with mirrors or something

    is there any way to get the blue, in the stream, with the red and green without a dichro?
    i have a dichro to pass the green and reflect the red already.
    could you maybe reflect it off a mirror, knife edging, or some thing like that?
    see i am a muscian first, not a laserist, so i don't need it to be perfect, just want to do some simple effects.
    any answeres would be great, and any pictures, if anyone knows how to do this.
    thanks and God bless.
    God Bless.

    No.


    Longer answer: If your red and green are both of the same polarization then you might be able to use a polarization beam splitter cube, but a dichro is easier.

    And probably cheaper than a broadband PBS cube too.

    I wonder if anyone uses a dispersive prism to combine beams? Perhaps two knife edge mirrors to keep it all compact?
