Abstract: A triangulation light sensor includes at least one light transmitter for transmitting a light signal into a detection zone, a light receiver having a plurality of receiver elements for receiving light from the detection zone reflected diffusely and/or specularly, and a reception optics arranged between the detection zone and the light receiver in the beam path, with the position of a light spot produced on the light receiver in a triangulation direction by the reflected light resulting in dependence on the distance of the object. The reception optics includes at least one multisegmented lens element having a plurality of lens segments with mutually spaced apart optical axes in the triangulation direction and at least one freeform lens element or one diffractive-optical element having a multisegmented lens element having a plurality of lens segments with optical axes spaced apart from one another in the triangulation direction.

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.

Abstract: An optoelectronic sensor (10) according to the principle of triangulation for detecting an object (36) in a monitoring region (18) comprises a light transmitter (12) and a spatially resolving light receiver (26). A receiving optics (22) and an optical element (24) are arranged in front of the light receiver (26), wherein the optical element (24) comprises a converging partial region (24a) and a diverging partial region (24c) and is arranged such that a remitted light bundle (20) from an object (36) in a near range of the monitoring region (18) passes through the converging partial region (24) and a remitted light bundle (20) from an object (36) in a far range of the monitoring region (18) passes through the diverging partial region (24c).

Abstract: An optoelectronic sensor for recognizing object edges of objects comprises at least three light transmitters which are arranged such that at least two different spacings result between two respective light transmitters. For recognizing an object edge, an evaluation unit is configured to carry out a common evaluation of an image taken by a light receiver of a light spot generated by the transmitted light beams of a first light transmitter and of an image taken by a light receiver of a light spot generated by the transmitted light beams of another light transmitter. The pair of light transmitters to be used for the common evaluation can be selected in dependence on a selection criterion from at least two differently spaced apart pairs of light transmitters.
