Beschreibung
Zusammenfassung:	An optoelectronic sensor for recognizing objects or object properties comprises a light transmitter for transmitting transmitted light into a detection zone, a light receiver for receiving received light and an evaluation unit which is configured to detect an object located in or projecting into a detection zone and/or to determine a property of such an object with reference to the received light received by the light receiver. The light transmitter comprises a monolithic semi-conductor component having a first light emitting layer and a second light emitting layer, with the first light emitting layer being configured for emitting red light and the second light emitting layer being configured for emitting infrared light, and with the second light emitting layer defining a central light emitting surface and the first light emitting layer defining an outer light emitting surface surrounding the central light emitting surface.
