Would it be impossible to just add the yellow in the power train somewhere that allows you to a less specific dichro? It seems like moving a the optics around a bit would be cheaper than a custom optic...
I just put a phone call into my medical friend, about the HGM "K" model dichro.
Email the seller on Ebay I told you about, and tell him what you need.

yes the obvious solution is to put it in the middle of the optical chain, but its my least powerful (and most expensive/mW) so I wanted to have it as close to the scanners as possible to maximize the amount of 593 that actually gets used
will do
