Abstract
A beam splitter is disclosed in which a light beam entering a block of light-transmitting material is internally reflected a plurality of times between a pair of parallel sides, one side being coated to enhance such internal reflection and the other side having in the direction of its length a succession of areas which are differently coated to control the amount of the beam which is reflected internallly and the amount of the beam which emerges; a plurality of parallel emergent beams of substantially equal intensity can be obtained in this way. The application of such a beam splitter to an image-reproducing system is described, the beams contributing to the formation of half-tone dots in the image.
