Publication number: 20240105837Abstract: A power semiconductor device is proposed. The power semiconductor device includes a semiconductor body and a wiring area over a first surface of the semiconductor body. The power semiconductor device further includes a bipolar power semiconductor element including a first load electrode in the wiring area, an active area in the semiconductor body, and a second load electrode at a second surface of the semiconductor body. The power semiconductor device further includes a current sensing element including a pn or pin junction. The power semiconductor device further includes an optical window configured to allow electromagnetic radiation caused by an on-current of the bipolar power semiconductor element to pass to the current sensing element.Type: ApplicationFiled: September 12, 2023Publication date: March 28, 2024Inventors: Ingo Dirnstorfer, Andreas Gneupel, Dmitry Balashov, Markus Böhm, Christian Kemle, Richard Springer

Patent number: 9348130Abstract: A device for holding filters for a microscope includes a filter wheel (20) rotatable about an axis of rotation (16) and a drive unit (14) for rotating the filter wheel (20). The filter wheel (20) comprises a basic body (44) rotatable about the axis of rotation (16) and at least one segment (46-54) selectively connectable to the basic body. The segment (46-54) comprises at least two housing areas (58, 59) each holding at least one filter (11). Another housing area may provide a transmission range (36, 59) for unfiltered transmission of light. A second rotatable filter wheel may be arranged at a location displaced along the axis of rotation relative to the filter wheel, and may have its own respective transmission range for unfiltered transmission of light, whereby a filter on either filter wheel may be aligned with the transmission range on the other filter wheel.Type: GrantFiled: June 13, 2014Date of Patent: May 24, 2016Assignee: Leica Microsystems CMS GmbHInventors: Ingo Böhm, Dirk-Oliver Fehrer

Patent number: 7660035Abstract: A scanning microscope includes at least one light source, an acousto-optical element, a beam deflection device and a beam guiding device. The at least one light source generates an illuminating light beam. The acousto-optical element spatially splits a sub-light beam from the illuminating light beam and adjusts an optical power of the illuminating light beam. The beam deflection device scans the illuminating light beam over or through a sample. The beam guiding device directs the sub-light beam onto the sample.Type: GrantFiled: October 13, 2004Date of Patent: February 9, 2010Assignee: Leica Microsystems CMS GmbHInventors: Ingo Böhm, Heinrich Ulrich, Werner Knebel
