Abstract: A light sensing device having background suppression includes: a light transmitter, a light receiver, an evaluation unit for determining the spacing between the light sensing device and an object in a detection zone of the light sensing device, and a setting element for setting a sensing depth within which an object should be detected. A critical spacing region is defined between a set sensing depth and a background in dependence on the set sensing depth. A signal output outputs a signal if an object is detected within the set sensing depth and a display unit displays whether an object is present within the sensing depth. The set sensing depth can be displayed in relation to a maximum sensing depth of the light sensing device in a first display region and a second display region indicates if an object is located in the critical spacing region.

Abstract: 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.
