Patent number: 11921274Abstract: Detecting emission light, in a laser scanning microscope, wherein the emission light emanating from a sample is guided onto a two-dimensional matrix sensor having a plurality of pixels and being located on an image plane, and a detection point distribution function is detected by the matrix sensor in a spatially oversam pled manner. The emission light emanating from the sample is spectrally separated in a dispersion device; the spectrally separated emission light is detected by the matrix sensor in a spectrally resolved manner; and during the analysis of the intensities measured by the pixels of a pixel region, the spectral separation is cancelled at least for some of said pixels. Additional aspects relate to a detection device for the spectrally resolved detection of emission light in a laser scanning microscope and to a laser scanning microscope.Type: GrantFiled: July 29, 2021Date of Patent: March 5, 2024Assignee: Carl Zeiss Microscopy GmbHInventors: Daniel Schwedt, Tiemo Anhut, Peter Schacht

Patent number: 11774706Abstract: The invention relates firstly to a method for determining a mechanical deviation on a displacement path of an optical zoom lens, in particular on a displacement path of an optical zoom lens of a microscope. The optical zoom lens is arranged in a beam path between an object to be recorded and an electronic image sensor. In a first method step, an optical marker is introduced into the beam path at a position of the beam path located between the object to be recorded and the optical zoom lens, such that the optical marker passes the optical zoom lens and then is depicted on an image in which a position of the optical marker is detected and determined. This is compared with a reference position of the optical marker in order to determine the mechanical deviation on the displacement path of the optical zoom lens. The invention further relates to a method for correction of a displacement error of an image recorded by an electronic image sensor and to an electronic image recording device.Type: GrantFiled: July 11, 2022Date of Patent: October 3, 2023Assignee: CARL ZEISS MICROSCOPY GMBHInventors: Daniel Stegmann, Daniel Harangozo, Peter Schacht, Thomas Milde

Patent number: 11194148Abstract: An objective-changer apparatus for a microscope system comprising an objective-transfer element with at least one objective holder for holding an objective that has been provided with an adapter, wherein the objective-transfer element moves a selected active objective into position in a transfer position in controlled fashion and an objective axis of the active objective does not coincide with the optical axis of the microscope system in the transfer position. A receiving apparatus is adjustable in the direction of the optical axis of the microscope system and can be brought into contact with the adapter. The receiving apparatus transports the active objective along a transport path in a transport direction orthogonal to the microscope system's optical axis between the transfer position and a work position in line with the microscope system's optical axis. The transport path is shorter than the extent of the objective holder in the transport direction.Type: GrantFiled: April 17, 2019Date of Patent: December 7, 2021Assignee: Carl Zeiss Microscopy GmbHInventors: Saskia Pergande, Ingo Fahlbusch, Peter Schacht, Daniel Stegmann

Patent number: 5109898Abstract: Multi-ply floor panel boards are cut from a sheet composed of individual, glued plies. The plies of two such sheets are now placed together underside to underside and glued together. Then double board blanks in the size of the panel boards to be manufactured are cut from the composite sheet formed in this way. After hardening of the glue, these double board blanks are halved along their middle plane, so that two panel boards completely free of warping are formed. The plies adjoining the middle plane of the composite sheet preferably form a continuous middle ply. This can be provided on both sides with incisions reaching to the middle plane, so that, after halving of the double board blanks, each panel board has a bottom ply with continuous parting cuts. The grooves and tongues that are sometimes necessary along the edges of the panel boards are already made in the edges of the double board blanks in one working cycle for each two panel boards.Type: GrantFiled: March 14, 1990Date of Patent: May 5, 1992Inventor: Peter Schacht

Patent number: 3942295Abstract: The baseboard arrangement includes a fairing unit, which is used in conjunction with a baseboard member of the type comprised of a flat foot portion adapted to lie flat against a floor surface and a vertical wall-facing portion adapted to lie flat against the meeting wall surfaces of a projecting corner of a room or corridor, for example. The flat foot portion of the baseboard member is slitted in direction transverse to the elongation of the baseboard member, with the slit terminating at the vertical wall-facing portion of the baseboard member. Accordingly, the baseboard member, at the region of such slit, can be bent around the projecting corner, thereby causing the slit to spread and form a larger corner gap. The fairing unit includes two flat leg portions adapted to lie flat against the floor surface along the meeting walls of the projecting corner, underneath part of the foot portion of the baseboard member, and these leg portions enclose a substantially right angle.Type: GrantFiled: March 26, 1974Date of Patent: March 9, 1976Inventor: Peter Schacht
