Optical encoder

An optical encoder comprising:

• an emitter;
• a receiver;
• a reflector;
• and
• a code carrier
• wherein the emitter emits electromagnetic radiation along an emission axis in a direction of the reflector;
• wherein the reflector has at least one reflection section that deflects the electromagnetic radiation along a reception axis in a direction of the receiver;
• wherein the code carrier is movably supported and has a sequence of code sections to interrupt the emitted electromagnetic radiation or to give way for the emitted electromagnetic radiation to impinge on the receiver in dependence on a 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 a range from 30 degrees to 150 degrees;
• and
• wherein at least one interruption section of the reflector, which is arranged adjacent to the at least one reflection section and which interrupts the emitted electromagnetic radiation, forms an additional code section.
