  • Optical zoom system for a light scanning electron microscope
    Patent number: 7369305
    Abstract: For a confocal scanning electron microscope (1) an optical zoom system (41) is provided, which not only makes a zoom function possible, in that a variable magnification of an image is possible, but rather which additionally produces a pupil image in the illuminating beam path (IB) [BS] and thereby makes a variable imaging length possible (distance between the original pupil (En.P) [EP] and the imaged/reproduced pupil (Ex.P) [AP]) so that axially varying objective pupil positions can thereby be compensated.
    Type: Grant
    Filed: October 19, 2004
    Date of Patent: May 6, 2008
    Assignee: Carl Zeiss Jena GmbH
    Inventors: Ralf Wolleschensky, Joerg Steinert, Michael Goelles, Kristina Uhlendorf

  • Optical zoom system for a light scanning electron microscope
    Publication number: 20060049343
    Abstract: For a confocal scanning electron microscope (1) an optical zoom system (41) with point plotting light source distribution is provided, which not only makes a zoom function possible, in that a variable magnification of an image is possible, but rather which additionally produces a pupil image in the illuminating beam path (IB) [BS] and thereby makes a variable imaging length possible (distance between the original pupil (En.P) [EP] and the imaged/reproduced pupil (Ex.P) [AP]) so that axially varying objective pupil positions can thereby be compensated.

  • Optical zoom system for a light scanning electron microscope
    Publication number: 20060011832
    Abstract: For a confocal scanning electron microscope (1) an optical zoom system (41) with linear scanning is provided, which not only makes a zoom function possible, in that a variable magnification of an image is possible, but rather which additionally produces a pupil image in the illuminating beam path (IB) [BS] and thereby makes a variable imaging length possible (distance between the original pupil (En.P) [EP] and the imaged/reproduced pupil (Ex.P) [AP]) so that axially varying objective pupil positions can thereby be compensated.
