Abstract: An apparatus comprising a transmission unit comprising a light element that is configured to emit light in a predefined wavelength range; and a transmission optics that is configured to direct the emitted light to an object; a reception unit comprising a first reception element; a second reception element that is arranged spaced apart from the first reception element; and a reception optics that is configured to receive light remitted by the object and to direct it to the first reception element and the second reception element; and an evaluation unit that is configured to evaluate light received by the first reception element and to determine a distance of the object and to evaluate light received by the second reception element and to determine a color of the object.

Abstract: The invention relates to an optical sensor having a light transmitter for transmitting transmitted light into a detection zone, having a first and a second light receiver which are configured for receiving received light from the detection zone which is reflected in a reflective or diffuse manner and for generating received signals from the received light, and having an evaluation unit for generating a detection signal from the received signals. The light receivers are arranged such that each light receiver receives a portion of the received light. Each light receiver has an effective reception surface, with the effective reception surface of the second light receiver being smaller than the effective reception surface of the first light receiver such that the ratio between the received signal generated by the first light receiver and the received signal generated by the second light receiver depends on the sensing distance of the detected object.

Abstract: The present invention relates to an optoelectronic sensor system for detecting objects in a monitored zone having a light transmitter for transmitting light into the monitored zone along a transmitted light path, having a light receiver for receiving received light from the monitored zone that is remitted along a received light path in the direction of the light receiver from an object to be detected in the monitored zone or a reflector bounding the monitored zone, and having an objective arrangement arranged in front of the light transmitter and the light receiver. The transmitted light path and the received light path run spaced apart from one another at least in part sections facing the light transmitter and the light receiver respectively. It is proposed that the objective arrangement has a first objective region and a second objective region laterally spaced apart from the first objective region, wherein the transmitted light path runs through the first objective region and that the sensor system has a reception space provided between the objective arrangement, on the one hand, and the light transmitter and the light receiver, on the other hand, in which reception space at least one deflection element can selectively be introduced that is configured to deflect or define the received light path such that it runs through the first objective region with an introduced deflection element and through the second objective region with a deflection element not introduced.
