Patents by Inventor Alexander Thesen

Alexander Thesen has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Microscopic examination of an object using a sequence of optical microscopy and particle beam microscopy
    Patent number: 11454797
    Abstract: A slide system for optical microscopy using immersion fluid including a cover glass having a first refractive index and a transparent film having a second refractive index. The second refractive index of the transparent film is matched to the first refractive index of the cover glass. The transparent film protects the cover glass from immersion fluid used for optical microscopy and the transparent film is configured such that the immersion fluid used can be removed by lifting off the transparent film.
    Type: Grant
    Filed: October 3, 2019
    Date of Patent: September 27, 2022
    Assignee: Carl Zeiss Microscopy GmbH
    Inventors: Christian Thomas, Torsten Sievers, Alexander Thesen

  • Microscopic examination of an object using a sequence of optical microscopy and particle beam microscopy
    Patent number: 9581799
    Abstract: For the microscopy of an object using a combination of optical microscopy and particle beam microscopy, a microscope slide system comprises an electrically conductive holder, wherein at least one window is configured in the holder, and wherein the holder has the dimensions of a standard glass microscope slide for the optical microscopy; a microscope slide element, which is designed to carry the object for the microscopy and which is designed such that the element can be placed over the window; and a fastening device, which is designed to fix the microscope slide element over the window. By means of said microscope slide system, the object can be analyzed using separate microscopes, without having to relocate the object.
