  • Patent number: 11060955
    Abstract: A microtome for producing thin sections from a sample includes a sample holder configured to receive the sample and a cutting edge configured to cut the sample, the cutting edge having a specified cutting direction, the cutting direction and the cutting edge spanning a cutting plane. The microtome further includes a movement device configured to produce a relative movement between the sample holder and the cutting unit for cutting the sample in the cutting direction, a feed device configured to produce a relative movement between the sample holder and the cutting edge for cutting the sample in a feed direction at an angle not equal to 0° to the cutting plane, and a liquid volume with a liquid abutting the cutting edge on a side of the cutting edge facing away from the sample holder.

  • Patent number: 9464995
    Abstract: Methods and devices for magnified imaging of three-dimensional samples are disclosed. The methods include imaging sample sections of a sample section series using a first particle-optical device. Coordinates of the imaged sample point are acquired and stored in such a way that the coordinates of the imaged sample point can be associated with the respective image of this sample point. The method also includes selecting a volume of interest (VOI), and transmitting the coordinates of the selected VOI to a second particle-optical device. In addition, the method includes imaging the selected VOI by means of the second particle-optical device. A plurality of planes of a sample section are imaged in order to obtain a 3D image of the selected VOI.

  • Patent number: 8436302
    Abstract: A phase-shifting element for shifting a phase of at least a portion of a particle beam is described, as well as a particle beam device having a phase-shifting element of this type. In the phase-shifting element and the particle beam device having a phase-shifting element, components shadowing the particle beam are avoided, so that proper information content is achieved and in which the phase contrast is essentially spatial frequency-independent. The phase-shifting element may have at least one means for generating a non-homogeneous or anisotropic potential. The particle beam device according to the system described herein may be provided with the phase-shifting element.
