    Nice to see those since that's about what I'm looking at for mine. I'm sure I'm not looking forward to finding out how much that 1.5 Kvant costs!

    Nice case...

    Smart-move, too, cause there's 'room to gro', and with these layouts (breadboard, up-top) you can always slap a 50/50 on a flag, in there, port the beam up / out, and make them a 'combo' beam-table / scans sys, ie:

    Default Dichro source

    Pure awesomeness!

    I note the beam path is blue-green-red. This makes the most sense to me as the blue has the most mojo to punch through 2 dichros, the red the least.

    I am building my first RGB and have planned a similar path. But I'm having a problem locating a good reflect blue/pass green dichro.

    If it isn't a trade secret, what is the source of the dichros?

    Thanks much.

    Out of interest, what percentage of the total component cost does the red make up? (roughly)

    Looks awesome Marc! You are a true master.

    I had the same questions as Mario about the beam path. It looks like the blue bounces off a mirror into a blue/green PBS cube, then the combined blue and green bounce off a mirror into a red dichro. Do i have that right?
