Abstract: The charged particle beam device comprises: an electron gun for generating an electron beam; an imaging lens system for imaging the electron beam that has passed through a sample; a splitting portion where the electron beam that has passed through the imaging lens system is split into a first image component and a second image component; a first image detection unit for detecting the first image component and outputting a first image; a second image detection unit for detecting the second image component and outputting a second image; a processing unit; and display units. The magnification for the second image is greater than the magnification for the first image. The processing unit generates a third image by combining the first image and the second image, and the display units display the second image and the third image.

Abstract: To improve the workability of the task of adjusting the position of a limit field diaphragm. An electron microscope provided with an image-capturing means for capturing an image of an observation visual field prior to insertion of a limit field diaphragm as a map image, a recording means for recording the map image, an extraction means for capturing an image of the observation visual field after insertion of the limit field diaphragm and extracting the outline of the diaphragm, a drawing means for drawing the outline on the map image, and a display means for displaying the image drawn by the drawing means.
