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. The telescope (11) images a first pupil (31) formed in the pupil plane (30) in a smaller second pupil (32), and transfers a beam of the illumination light (8) collimated in the second pupil (32) into an expanded beam collimated in the first pupil (31).Type: GrantFiled: November 30, 2020Date of Patent: March 7, 2023Assignee: ABBERIOR INSTRUMENTS GMBHInventors: Joern Heine, Haugen Mittelstaedt, Matthias Reuss, Gerald Donnert

Patent number: 11460618Abstract: An apparatus for selectively shaping phase fronts of a first light beam that is incident along an optical axis and that has a first linear input polarization direction running orthogonal to the optical axis comprises birefringent optical material arranged in all or all bar one of at least three different partial areas that follow to one another in a direction around the optical axis.

Publication number: 20220244515Abstract: In a first step of a method of microscopically recording images of samples extending in three dimensions, a first sectional image that is parallel to an optical axis of a microscope objective lens is recorded by scanning a sample with a focused excitation light distribution in a sectional area parallel to the optical axis of the microscope objective, wherein the excitation light distribution is corrected by a correction device according to initial adjustment values for adjustment parameters of an aberration correction function. In a second step, the first sectional image is evaluated. In a third step, new adjustment values for the adjustment parameters are defined. In a fourth step, further image data are recorded by scanning the sample with the focused excitation light distributions, wherein the excitation light distribution is corrected by the correction device according to the new adjustment values for the adjustment parameters of the aberration correction function.Type: ApplicationFiled: April 11, 2022Publication date: August 4, 2022Inventors: Matthias Reuss, Jörn Heine, Christian Wurm

Patent number: 11131630Abstract: For setting a laser-scanning fluorescence microscope to a correct alignment in which an intensity maximum of excitation light and an intensity minimum of fluorescence inhibition light coincide in a focal area of an objective lens, a structure in a sample marked with a fluorescent dye is scanned with the intensity maximum of the excitation light to generate first and second pictures of the sample, the first picture corresponding to a higher and the second picture corresponding to a lower intensity of the fluorescence inhibition light. A spatial offset of a first image of the structure in the first picture with regard to a second image of the structure in the second picture is calculated; and the intensity maximum of the excitation light is shifted with regard to the intensity minimum of the fluorescence inhibition light in the direction of the offset calculated to set the microscope to the correct alignment.Type: GrantFiled: February 26, 2019Date of Patent: September 28, 2021Assignee: ABBERIOR INSTRUMENTS GMBHInventors: Joern Heine, Matthias Reuss, Benjamin Harke, Lars Kastrup

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
