摘要： A method of manufacturing an optoelectronic sensor (10) is provided that has a reception unit (22) having a reception optics (24), a light receiver (28), and a diaphragm (26) therebetween, wherein the diaphragm (26) is arranged in a focal plane of the reception optics (24) so that a received light beam (20) generated by the reception optics is incident through the diaphragm aperture (42) of the diaphragm (26) at the point of smallest constriction. The diaphragm (26) is manufactured as an individual diaphragm using the reception optics (24).

摘要： An optoelectronic sensor for detecting an object in a monitored zone is provided having a light transmitter for transmitting transmitted light of a wavelength range; having a light receiver for producing a received signal from the transmitted light remitted at the object; having a reception optics that is arranged upstream of the light receiver and that has an optical filter adapted to the wavelength range for suppressing extraneous light; and having a control and evaluation unit that is configured to produce a piece of object information from the received signal, An adjustment device for changing the angle of incidence of the remitted transmitted light on the optical filter is provided here.

摘要： An optoelectronic sensor for detecting an object in a monitored zone is provided that comprises a light transmitter for transmitting transmitted light, a light receiver having a plurality of light reception elements operable in Geiger mode for receiving transmitted light remitted in the monitored zone, a reception optics arranged upstream of the light receiver and having a diaphragm, and a control and evaluation unit that is configured to determine a distance from the object with reference to a received signal of the light receiver from a time of flight between the transmission of the transmitted light and the reception of the remitted received light, wherein the diaphragm comprises a diaphragm substrate having at least one metallic layer and one diaphragm aperture. In this respect, a contact region of the metallic layer for potential equalization is electrically conductively connected to another component of the sensor.

摘要： An optoelectronic sensor for detecting objects in a monitored zone is provided that has a light transmitter for transmitting at least one scanning beam, a movable first deflection unit for a periodic deflection of the scanning beam in a first direction, a light receiver for generating a received signal from the scanning beam remitted by objects in the monitored zone, and a control and evaluation unit that is configured to evaluate the received signal to determine the distance from an object scanned by the scanning beam using a time of flight process, A second deflection unit is here configured to additionally deflect the scanning beam in the first direction and/or in a second direction transverse to the first direction without a movement or at most with micromechanically moved elements.
