    Abstract: PROBLEM TO BE SOLVED: To provide a method capable of more satisfactorily performing translucent charged-particle microscope observation of a sample including a relatively fine volume structure.SOLUTION: In order to perform tomographic imaging of a sample by means of a charged-particle microscope, the method includes the steps of: irradiating a sample on a tilted sample holder with a beam of charged particles, detecting the translucent beam at an image detector, and generating and capturing an image of the sample; repeating this procedure at each of a series of sample tilts so as to acquire a corresponding set of images; and mathematically processing the images included in the set in a reconfiguration step to construct a composite image of the sample. In the imaging step, a sequence of component images can be acquired at a corresponding sequence of focus settings regarding the given sample tilt. In the reconfiguration step, a plurality of component images in the sequence of component images are used with at least one tilt of the series of sample tilts in the step of mathematically processing the images. As a result, a 3D imaging cube rather than a 2D imaging sheet is rendered at the given sample tilt.

    Abstract: PROBLEM TO BE SOLVED: To provide a composite lens comprising an electron detector for giving information on energy and/or angle distribution of back scattering electrons.SOLUTION: A composite objective lens for a scanning electron microscope comprises: a conventional magnetic lens which is excited by a first lens coil; an immersion magnetic lens which is excited by a second lens coil; and an immersion electrostatic lens which is excited by a potential difference between a specimen 100 and an electrode 114. An electron beam 102 is converged on the specimen 100 by combining excitation of the first lens coil and the second lens coil. An excitation ratio of the first lens coil and the second lens coil is adjusted, thereby changing a distance from an optical axis in the case where back scattering electrons collide with an electron detector. Thus, a composite lens comprising a pixelated electron detector or an electron detector formed from annular bodies 205, 206, 207 for detecting back scattering electrons 202, 203, 204 is functioned as an energy selection detector.
