Abstract
There is provided an optical device, including a light-transmitting substrate having two major surfaces parallel to each other and two edges, optics for coupling light into the substrate by internal reflection. One of the edges is slanted with respect to the major surfaces and a portion of the optics for coupling light into the substrate is in contact with, or located adjacent to, the slanted edge.
