1. An optical device comprising:
an entrance surface to receive light from a light source;
an exit surface parallel to the entrance surface; and
a set of sidewalls, wherein each sidewall has a plurality of sections, each section adapted to reflect light with a direct transmission path from the entrance face to that section such that the light is reflected to the exit surface to be incident on the exit surface at less than or equal to a critical angle at the exit surface, and wherein an area of the exit surface, a distance between the entrance surface and exit surface and sidewall shapes are selected so that the optical device is configured to emit at least 70% of the light entering the separate optical device through the entrance surface from the exit surface in the selected half angle.
