In a method of manufacturing an optical system that comprises at least one beam deflection unit, at least one diaphragm element, and at least one holder for fixing the beam deflection element and the diaphragm element in a predefined arrangement relative to one another, the beam deflection element and a screening element are provided. The beam deflection element and the screening element are fixed by means of the holder such that the actual arrangement of the screening element relative to the beam deflection element corresponds to the predefined arrangement of the diaphragm element relative to the beam deflection element. The beam deflection element is irradiated by the processing light beams such that after a deflection by the beam deflection element the processing light beams are incident on a functional zone of the screening element and change its optical properties by energy emission.

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.

Optoelectronic sensor system

To allow a simple cascading without any optical crosstalk at the connection points, an optoelectronic sensor is provided having at least one electronic card which has light transmitter elements and/or light reception elements and having at least two optical modules which can be fastened to the electronic card, wherein each optical module comprises a tube array, which has a plurality of tubes, an open end and a closed end, wherein the open end of the optical module comprises an open first connection element of a connection to the tube array and comprises wall connection elements and wherein the closed end of the optical module comprises a closed second connection element of the connection which has an outer wall which is formed with shape matching to the wall connection elements of the open end of the optical module such that, on a plugging together of an open end of an optical module and of a closed end of a further optical module, the two connection elements of the connection form a connection tube which is like the tubes of the tube array.

The invention relates to a light grid having divergent light beams so that cross-beams can also be evaluated beside parallel beams, wherein not only a light beam interruption, but also the intensity of the light incidence on a light reception unit is evaluated. To provide an improved light grid with which in particular smaller objects can be detected and possibly also located, it is proposed that the light transmission units have a transmission optics in whose focus an extended light source is arranged. Furthermore, each beam contains an effective beam, with an effective beam being defined in that a part shading of this effective beam effects a measurable intensity change in the associated light receiver corresponding to the shading. Finally, the effective beams define at least one detection zone in the monitored plane, with an illumination by at least one effective beam being present in the total detection zone.
