Abstract
An optical arrangement is described having a plurality of light transmitting transmitter elements and/or receiver elements, a plurality of diffractive/refractive optical elements and a transparent front cover, in particular a front plate. The diffractive/refractive optical elements are arranged on a uniform carrier element formed in one piece. The carrier element is formed by the front cover, with the diffractive/refractive optical elements being directly formed in the front cover, and in particular being pressed into or moulded into the latter. The transmitter elements and/or the receiver elements are arranged on a uniform circuit board formed in one piece. Furthermore a light grid is described having such optical arrangements, and also a method for the manufacture of the required components for such optical arrangements.
