Publication number: 20220283422Abstract: An optical imaging device for a microscope includes an objective and an optical system configured to interact with the objective for optically imaging an object selectively in a first operating mode and a second operating mode. The optical system includes a first optical subsystem associated with the first operating mode, and a second optical subsystem associated with the second operating mode. The first optical subsystem is configured to form a first image of the object with a first magnification. The second optical subsystem is configured to form a second image of the object with a second magnification that is less than the first magnification. The second optical subsystem includes an optical module insertable into the optical path for selecting the second operating mode. The optical module includes a lens element with a positive refractive power.Type: ApplicationFiled: August 27, 2019Publication date: September 8, 2022Inventors: Christian SCHUMANN, Christian SCHULZ, Arnold MUELLER-RENTZ, Andreas LOTTER

Patent number: 11131840Abstract: A microscope system includes a detection unit having a color beam splitter arrangement with three beam splitter prisms, each having first, second and third prism surfaces. The first prism surfaces face in the same direction and are oriented parallel to one another at a right angle to an optical axis. The first and second prism surfaces are oriented in each case at acute angles to one another. The second and third prism surfaces are oriented in each case at right or obtuse angles to one another. The third and first prism surfaces are oriented in each case at acute angles to one another. A prismatic compensation element having first and second prism surfaces is assigned to each prism. The second prism surface of each of the compensation elements is arranged in a common plane with or parallel to the second prism surface of the respectively assigned prism.Type: GrantFiled: November 27, 2018Date of Patent: September 28, 2021Assignee: LEICA MICROSYSTEMS CMS GMBHInventors: Arnold Mueller-Rentz, Christian Schulz

Publication number: 20200201014Abstract: A microscope for examining a sample in phase contrast transmitted light illumination and/or in fluorescence reflected light illumination includes a phase contrast transmitted light illumination device, a fluorescence reflected light illumination device and an objective with a phase ring. The phase contrast transmitted light illumination device comprises a transmitted light illumination source and a transmitted light illumination optical unit with a ring stop. The ring stop comprises a light-opaque inner stop region which is surrounded by an at least partly light-transmissive ring-shaped region. The fluorescence reflected light illumination device comprises a reflected light illumination source and a reflected light illumination optical unit. A fluorescence reflected light illumination beam path produced by the fluorescence reflected light illumination device will lie, in terms of its cross section, within the inner stop region of the ring stop o after passing through an object plane of the microscope.Type: ApplicationFiled: May 16, 2018Publication date: June 25, 2020Inventors: Benjamin Deissler, Arnold Mueller-Rentz

Patent number: 9772482Abstract: An illumination device for an optical device, a microscope or a macroscope includes a first illumination source configured to emit light which is directed via an illumination beam path onto an object to be illuminated that is arranged in an object plane. At least one second illumination source is positionable in the illumination beam path, and is transparent or semitransparent as well as self-luminous. The at least one second illumination source is configured to allow light emitted from the first illumination source to pass through at least in part. The object plane having the object to be illuminated is configured to be illuminated both by the first and by the at least one second illumination source.Type: GrantFiled: October 22, 2013Date of Patent: September 26, 2017Assignee: LEICA MICROSYSTEMS CMS GMBHInventors: Christian Schumann, Ralf Krueger, Tobias Bauer, Arnold Mueller-Rentz, Klaus Hermanns, Christian Schulz

Patent number: 9250432Abstract: A microscope illumination system includes a first light source configured to provide light along an optical axis and an aperture device including an aperture wheel that is rotatable about an axis of rotation. The aperture wheel includes a plurality of apertures of varying size disposed circumferentially on the aperture wheel. The aperture wheel is rotatable so as to dispose each of the apertures in a position that is centered on the optical axis so as to generate an illumination beam path that extends in a centered relationship with respect to the optical axis, and so as to dispose each of the apertures in a position that is off-center from the optical axis and that is within a defined region around the optical axis so as to generate an illumination beam path that extends off-center from the optical axis for oblique incident illumination.Type: GrantFiled: October 11, 2011Date of Patent: February 2, 2016Assignee: LEICA MICROSYSTEMS CMS GMBHInventors: Albrecht Weiss, Arnold Mueller-Rentz, Klaus-Peter Schwaab, Stefan Motyka

Patent number: 8331018Abstract: An optical system is described for merging a first and a second partial image beam emanating from a specimen into a resultant image beam allowing modification of the areal proportion of the respective first or second partial image beam in the resultant image beam. A stop arrangement comprises at least a first and a second movable stop element each comprising at least one stop region adapted to be brought into a working position with the first or second partial image beam. Movably arranged connecting means for connecting the two stop elements are provided to modify the respective areal proportions of the partial image beams in the resultant image beam by movement of the connecting means.Type: GrantFiled: September 1, 2009Date of Patent: December 11, 2012Assignee: Leica Microsystems CMS GmbHInventor: Arnold Müller-Rentz

Patent number: 6542251Abstract: An illumination and imaging device (2) for multiple spectral regions comprises an objective (21) that defines an optical axis (20). A beam splitter module (32) is arranged in the optical axis (20). Multiple light sources (35), from each of which an illuminating beam path (35a, 35b, 35c) proceeds, are associated with the beam splitter module (32). Also provided are multiple detectors (34), associated with each of which is an imaging beam path (34a, 34b). The illuminating beam paths (35a, 35b, 35c) and imaging beam paths (34a, 34b) have a common optical path segment in which the beam splitter module (32) is arranged. The illumination and imaging device (2) can advantageously be used in a coordinate measuring machine (1).Type: GrantFiled: August 23, 2001Date of Patent: April 1, 2003Assignee: Leica Microsystems Wetzlar GmbHInventor: Arnold Mueller-Rentz
