Patent number: 11163095Abstract: 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.Type: GrantFiled: November 11, 2019Date of Patent: November 2, 2021Assignee: SICK AGInventors: Johannes Eble, Matthias Opfolter

Publication number: 20200084850Abstract: The light grid according to the invention comprises several light emitting units for emitting light beams, several light receiving units which supply reception signals according to the incidence of light and which can receive the transmitted light beams to form the light grid in case the beam paths are free, receiving optics and an evaluation unit for evaluating the intensity of the incidence of light on the light receiving units. In order to increase the performance of the light grid by limiting the field of view of the light receivers, the receiving optics comprise a substrate having a microlens array and each microlens is associated with an aperture and the apertures are each at the focal point of the associated microlens.Type: ApplicationFiled: August 13, 2019Publication date: March 12, 2020Inventor: Johannes EBLE

Patent number: 9791594Abstract: 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.Type: GrantFiled: October 23, 2014Date of Patent: October 17, 2017Assignee: SICK AGInventor: Johannes Eble
