Publication number: 20230384224Abstract: Methods and a device for imaging a sample stained with multiple dyes are disclosed. The methods enable nanoscopic imaging with up to molecular resolution to be placed in the spatial context of microscopic images, or nanoscopic tracking of individual molecules to be performed in the spatial context of a microscopic image. The methods combine different light-optical microscopy techniques in a particularly efficient manner. Molecular resolution can be achieved by a localization microscopic method, in particular by localization according to a MINFLUX or STED-MINFLUX method. These methods are characterized by the fact that, on the one hand, they are particularly gentle on the sample during the steps that precede imaging with molecular resolution, and on the other hand, they make optimal use of the fluorescence photons during localization or enable optimal use.Type: ApplicationFiled: October 15, 2021Publication date: November 30, 2023Inventors: Gerald DONNERT, Benjamin HARKE, Winfried WILLEMER

Patent number: 11598943Abstract: A fluorescence microscope (10) includes a sample illumination beam path including a source (9) for illumination light, a first wave front modulator (24) for providing the focused illumination light (8) with a central intensity minimum, a beam splitter (26) and a second adjustable wave front modulator (34) arranged in a pupil plane (30) of an objective (20). A first detection beam path section including the second wave front modulator (34) and a telescope (11) and ending at the beam splitter (26) coincides with the sample illumination beam path. A separate second detection beam path section includes a detector (38) for luminescence light from a sample.

Patent number: 10488342Abstract: In methods of high-resolution imaging a structure of a sample, the structure being marked with fluorescence markers, the sample is subjected to a light intensity distribution including an intensity maximum of focused fluorescence excitation light to selectively scan partial areas of interest of the sample. Fluorescence light emitted out of the sample is registered and allocated to a respective location of the light intensity distribution in the sample. The subjection of the sample to at least one part of the light intensity distribution is terminated at each location of the light intensity distribution, if at least one criterion of the following criteria is met: (a) a predetermined maximum light amount of the fluorescence light emitted out of the sample has been registered, and (b) a predetermined minimum light amount of the fluorescence light emitted out of the sample has not been registered within a predetermined period of time.Type: GrantFiled: October 23, 2018Date of Patent: November 26, 2019Assignee: ABBERIOR INSTRUMENTS GMBHInventors: Andreas Schoenle, Christian Wurm, Benjamin Harke, Gerald Donnert

Publication number: 20170123197Abstract: A device comprises two polarization-selective optical elements for separately modulating wave fronts of two components of a collimated light beam, which are transversally polarized in orthogonal directions. The two polarization-selective optical elements are first and second partial areas of one spatial light modulator (SLM) diffracting the light beam in backward direction. A mirror arranged between the first and second partial areas of the SLM reflects the light beam coming from the first partial area towards the second partial area. A wave plate arranged between the first partial area and the second partial area of the SLM rotates the polarization directions of both components of the light beam by 90°. The mirror reflects the first and second components of the light beam as parallel bundles of light rays resulting in a lateral offset between the first and second components of the light beam behind the second partial area of the SLM.Type: ApplicationFiled: November 4, 2015Publication date: May 4, 2017Inventors: Matthias Reuss, Andreas Schoenle, Lars Kastrup, Gerald Donnert, Benjamin Harke
