Publication number: 20230013386Abstract: An adjusting device is provided for positioning an object. The adjusting device includes a base and a supply line. The base is configured to move an object that is connectable to the base in the connected state along a path of motion in a position-controlled manner. The supply line supplies the energy and/or signal transmission to and/or from the base. The supply line is coupled to the base in a reversibly detachable manner.Type: ApplicationFiled: December 9, 2020Publication date: January 19, 2023Inventors: Thomas BOCHER, Lukas RAU, Tomas NAVRATIL, Michael ERNST, Axel GRABOWSKI, Matthias SCHULZ

Patent number: 9964611Abstract: An NMR spectrometer (1?) has a sample changer (4?) with at least one cylindrical sample holder (7?, 7?) for receiving an elongated NMR sample at a loading position (5) and for transferring the NMR sample into the measurement volume at a transfer position (6). The sample holder is open in an upward direction and the cylinder axis of the cylindrical sample holder is inclined at the loading position by an angle of inclination a of between 30 and 60 degrees with respect to the vertical and it extends vertically at the transfer position. A positioning device is provided, which transfers the NMR sample at or after the transfer position into the measuring position in the measurement volume with a vertically aligned sample axis of the NMR sample. The spectrometer enables a more ergonomically favorable feed of the sample.Type: GrantFiled: August 13, 2014Date of Patent: May 8, 2018Assignee: Bruker BioSpin GmbHInventors: Thomas Bocher, Diether Maier, Volker Reiss

Patent number: 8040598Abstract: A microscope for observing an object selectably using the bright-field transmitted light contrast procedure or the incident-light fluorescence contrast procedure. During the bright-field transmitted light contrast procedure, an illumination beam path is directed from a bright-field light source to the object and an imaging beam path is directed from the object through the microscope objective into the microscope tube, which includes a fluorescence unit that includes a fluorescence excitation light source, an illumination optical system, a filter set having at least one excitation filter and at least one emission filter, as well as a beamsplitter. The fluorescence unit is mounted movably, so that in a first end position of movement the beamsplitter and the emission filter are out of the imaging beam path of the microscope and in a second end position of movement they are in the imaging beam path between the microscope objective and the microscope tube.Type: GrantFiled: June 12, 2008Date of Patent: October 18, 2011Assignee: Carl Zeiss MicroImaging GmbHInventors: Andreas Nolte, Thomas Bocher, Ingo Fahlbusch

Patent number: 7907348Abstract: The invention relates to a microscope objective with preferably anti-symmetric lenses or lens groups with an optical magnification of ?100 and a visual field factor of 20. According to the invention the microscope objective consists of 9 lenses with 3 cemented elements, starting from the object side (left), a lens which is almost a hemisphere L1 with positive refractive power, a meniscus lens L2 with positive refractive power, a two-part cemented element G1 with positive refractive power, another two-art cemented element G2 with positive refractive power, a two-part cemented element G3 with negative refractive power, and finally a meniscus lens L9 with negative refractive power. By using cemented elements and lens pairings of the same construction, production costs can be reduced compared with methods of the prior art while image contrast is improved.Type: GrantFiled: April 26, 2007Date of Patent: March 15, 2011Assignee: Carl Zeiss MicroImaging GmbHInventors: Renhu Shi, Werner Kleinschmidt, Thomas Bocher

Patent number: 7672057Abstract: A microscope objective having at least four lenses or groups of lenses and which can be used to improve image contrast. According to the invention, a phase plate, aligned concentrically to the optical axis, can be integrated into and taken out of the air space between the first lens and the second lens, as viewed from the object side. The defined arrangement of the phase plate and the associated shift of the real pupil into the air space between the first two lenses or groups of lenses, respectively, of the microscope objective allows a microscope objective, initially designed as a bright-field variant, to be redesigned as a phase contrast variant with relative ease.Type: GrantFiled: March 21, 2008Date of Patent: March 2, 2010Assignee: Carl Zeiss MicroImaging GmbHInventors: Renhu Shi, Anke Vogelgsang, Thomas Bocher, Werner Kleinschmidt

Publication number: 20090021826Abstract: The invention is directed to a light microscope with an external power supply unit. The microscope according to the invention has a receptacle for the external power supply unit in which it can be fastened in a removable manner. This receptacle is advantageously formed as a cutout in the microscope stand so that the power supply unit adapts to the outer shape of the microscope when seated in the receptacle.Type: ApplicationFiled: June 22, 2006Publication date: January 22, 2009Inventors: Ralph Aschenbach, Thomas Bocher

Publication number: 20080191895Abstract: The invention is directed to a light microscope with a display which is suitable for use particularly in lecture rooms or dissection rooms. By an integrated, large display of the viewing conditions, e.g., lamp voltage, selected objective, etc., that can be viewed from a distance, the actual state of the adjusted conditions can be determined from any position within a classroom or laboratory room.Type: ApplicationFiled: June 1, 2006Publication date: August 14, 2008Inventors: Ralph Aschenbach, Thomas Bocher, Matthias Kramer

Publication number: 20070146872Abstract: An optical microscope can be converted by the user quickly with a few movements of the hand so that it can be used as an upright variant or as an inverted variant. The required optical elements are accommodated in components that can be mechanically separated from one another and variously combined. The optical system is calculated in such a way that an upright microscope with vertical illumination or transmitted illumination or an inverted microscope with vertical illumination or transmitted illumination results when the components are combined in the required manner by interfaces provided for this purpose.Type: ApplicationFiled: November 4, 2004Publication date: June 28, 2007Applicant: CARL ZEISS JENA GmbHInventors: Thomas Bocher, Hans Tandler, Hubert Wahl, Hans Brinkmann, Reiner Mitzkus, Franz Muchel, Harald Schadwinkel, Peter Gretscher
