1. An optical component for transferring light between an electro-optical device and a light transmissive panel which defines two opposing boundary surfaces, the electro-optical device having an operative solid angle given by first and second device divergence angles in orthogonal first and second device planes, wherein the optical component comprises:
a first light transmission surface configured to face the electro-optical device, a second light transmission surface for mounting on one of the boundary surfaces, and a control surface arrangement configured to direct the light between the first and second light transmission surfaces by one or more reflections so as to expand the first device divergence angle into a first component divergence angle at the second light transmission surface, the first component divergence angle being arranged to define, with respect to light propagating by internal reflections inside the light transmissive panel, a divergence inside the light transmissive panel in a direction parallel to the boundary surfaces. |
