If I had a complete machine shop here I could probably build tiny lens mounts and use flat mirrors; but that would probably screw up the astigmatism and the dispersion. Besides, I don't have a machine shop.
I have a Coherent RED-Yellow RING set, but that set I'd have to sell you, but the price would be dirt cheap. Another PM please.
