Wavien, Inc. - CBT 90 – RLT
Lot's of marketing mumbo jumbo going on, but it looks like a similar concept - capturing the wide angle light and bouncing it around inside something reflective until it comes out the front. Anyone up for inverting a parabolic reflector over a XM-L and then sticking an aspheric on top?
That is, unless I'm just rehashing stuff that's already be done and discarded
