Abstract: A distortion measurement method for an electron microscope image includes: loading a distortion measurement specimen having structures arranged in a lattice to a specimen plane of an electron microscope or a plane conjugate to the specimen plane in order to obtain an electron microscope image of the distortion measurement specimen; and measuring a distortion from the obtained electron microscope image of the distortion measurement specimen.

Abstract: A transmission electron microscope (100) includes an electron beam source (2), an illumination lens (10), an objective lens (20), an intermediate lens system (30), a pair of transfer lenses (40) located behind the intermediate lens system (30), and an energy filter (60) for separating the electrons of the beam L transmitted through the specimen (S) according to energy. The transfer lenses (40) transfer the first image to the entrance crossover plane (S1) of the energy filter (60) and to transfer the second image to the entrance image plane (A1) of the filter (60). An image plane (A3) is formed between the first transfer lens (40a) and the second transfer lens (40b).

Abstract: There is provided an energy filter capable of being simplified in structure and of achieving low aberrations. The energy filter (100) includes a first sector magnet (10) and a second sector magnet (20). The first and second magnets (10, 20) are configured mirror-symmetrically with respect to a symmetry plane (M). There are one focal point of crossover in the X direction and one focal point of crossover in the Y direction. The focal point of crossover in the X direction and the focal point of crossover in the Y direction are at an energy dispersive plane (S2). There are two focal points of image in the X direction and two focal points of image in the Y direction. The focal points of image in the X direction and the focal points of image in the Y direction are at the symmetry plane (M) and at an achromatic plane (A2).

Abstract: An energy filter has a plurality of sector magnets which are configured symmetrically with respect to a symmetry plane, and forms a real image on the symmetry plane. The energy filter include: an entrance aperture provided with a slit having a longitudinal direction in a direction perpendicular to an energy dispersion direction; and a hexapole and a quadrupole disposed on the symmetry plane.
