    Abstract: PROBLEM TO BE SOLVED: To provide a correction device in which a chromatic aberration and an aperture aberration in a scanning electron microscope or a scanning transmission type electron microscope are removed.
    SOLUTION: The correction device is provided with four multipole elements arranged continuously in an optical path (9), and a first multipole element (1) and a fourth multipole element (4) are used in order to make 4-pole fields (5, 6), and a second multipole element (2) and a third multipole element (3) are used in order to make 8-pole magnetic fields (7, 8) and a 4-pole field, and the 4-pole fields of the above four multipole elements rotate continuously each in 90°, and the second (2) and the third multipole elements (3) are designed as a 12-pole element by using 12-pole fields (25, 26), and the additional 12-pole element (13) is inserted between the second (2) and the third multipole elements (3), and moreover, an 8-pole filed (14) is overlapped by a 12-pole field (15) in the additional 12-pole element (13).
