Looking for the best addition to a 635nm 200mw unit. I plan on knife edging two red diodes and then combining that with the 635 in a PBS cube. I am looking for suggestion on if i'd be better using the 650 closed can or the 660 LOC diodes for this. Or for that matter if the 650's even would work, I have scene it done with the 660's. Anyone care to share there thoughts?
Thanks
