Light transmission thru various plastic
Light transmission thru various plastic
(OP)
I need to construct a lamp using some sort of plastic about an inch thick to transfer light from one edge to the other. I need to know which material transmits the most light (least lumin loss) from a source - or which material has the least "resistance", so to speak. I need to put a light bulb near the edge of some sort of plastic, I was thinking either a piece of polyester resin, a urathane, or a polymethyl methacrylate (perspex), and I what I'm asking is which one (or one I haven't mentioned out of ignorance) will deliver the largest percentage of the source light out the opposite edge.
Thanks

Another possibility is one of the DuraStar grades of polyester from Eastman. It looks like they are in the range of 89-91% as well. You can obtain more information on their website:
