Abstract: The invention relates to a method for correcting distortions introduced by the projection system (106) of a TEM. As known to the person skilled in the art distortions may limit the resolution of a TEM, especially when making a 3D reconstruction of a feature using tomography. Also when using strain analysis in a TEM the distortions may limit the detection of strain. To this end the invention discloses a detector equipped with multipoles (152), the multipoles warping the image of the TEM in such a way that distortions introduced by the projection system are counteracted. The detector may further include a CCD or a fluorescent screen (151) for detecting the electrons.

Abstract: The invention relates to a blocking member to be placed in the diffraction plane of a TEM. It resembles the knife edge used for single sideband imaging, but blocks only electrons deflected over a small angle.
