Abstract

An optical encoder comprises an emitter; a receiver; a reflector; and a code carrier, wherein the emitter emits electromagnetic radiation along an emission axis in the direction of the reflector and the reflector deflects the electromagnetic radiation along a reception axis in the direction of the receiver. The code carrier is movably supported and has a sequence of code sections to interrupt or to give way for the emitted electromagnetic radiation to impinge on the detector in dependence on the position of the code carrier, wherein the emission axis and the reception axis extend at an alignment angle with respect to one another that has a value in the range from 30 degrees to 150 degrees.
