Abstract: There is disclosed a scanning electron charged-particle beam instrument in which the image does not escape during rotation even if the center of mechanical rotation is not coincident with the center of the image. The instrument is so operated that the center position of the image is fixed when a mechanical rotation is made if the center of mechanical rotation is not coincident with the center of the image. For this purpose, when the specimen stage assembly is rotated mechanically, the X-stage of the specimen stage assembly is driven to move in the X-direction. The Y-stage of the stage assembly is driven to move in the Y-direction. The distance L between the center of mechanical rotation and the moving speed of the X-Y stage are interlinked. The apparent speed of the rotational speed of the image on the viewing screen is made constant irrespective of the distance L. In practice, the moving speed of the X-Y stage is increased with increasing the distance L.

Abstract: There is disclosed a scanning electron microscope for producing images at different magnifications in such a way that these images can be easily compared. This microscope has a control unit that is set at two magnifications. These two magnifications are stored in their respective magnification memories. A first frame used for a comparison of the magnifications is displayed in a size F.sub.1 on a first CRT. A second frame used for a comparison of the magnifications is displayed in a size F.sub.2 on a second CRT. A magnification comparator finds these sizes F.sub.1 and F.sub.2 from the two magnifications and from the sizes of the viewing screens of the two CRTs. Signals indicating the sizes F.sub.1 and F.sub.2 are supplied to a magnification comparison frame display device, which produces frame signals to adders, where the frame signals are superimposed on the image signals. A frame indicating the scope of the image displayed on the second CRT is displayed on the first CRT.
