Abstract
A rear view system for a vehicle (10) includes in combination a light transmitting member (2) and a light reflective medium (16) spatially displaced from the member. The member has a first face (4) for light emergence from which in use light rays are directed towards the medium (16) and a second face (6) for light incidence, each face being disposed on a respective side of a median plane (8). The member (2) comprises a plurality of elemental prismatic sections, the prismatic angles of the elemental sections progressively changing along the length of the member whereby rays of refracted light emerging through the first face are in parallelism or substantial parallelism one with the other irrespective of the angles of incidence of the rays. The shape of the light transmitting member (2) is such as to afford a wide angular scope of view to the system thereby to enhance safety.
