I think I will stick with photons thanks very much!  :t:One for the Mavens:Which brings me to the part about what are the limits of transmission with an optical device ????????  Given that we use the most incrementally beneficial HT and Ultra-FL glass, as well as yet to be fully developed unobtanium spec glass, how high can the transmission go ??????????Say with PorroII prisms, and roughly 16 multicoated surfaces (of over 99.9% tr), then we should be up around 96.5% + transmission ..... is progress beyond that possible with upcoming technology on the drawing boards ??????  (increased transmission limits of multicoating, cold fusion, perfect surface finish vacuum joining, etc).  Surely the brightness gains, and reduction in stray light is worth it  ......   :cat: Chosun  :gh:</blockquote>
