 		 #145897 - just a thought
Responding to: ???'s previous message
In a totally different application I once used a partially transparent mirror set at 45 degrees one source going straight through and the other 'turned' by the morror. the picture here http://en.wikipedia.org/wiki/Beam_splitter show what I mean.

not a fan of wikipedia, but the google hit there and the picture fits, I did not check the words.
