Abstract: PURPOSE:To enable the easy switching between high magnification and low magnification and reduce the distortion of an image by providing an auxiliary lens for focusing an electron beam on a sample between the focusing lens and the objective lens. CONSTITUTION:An auxiliary lens 20 for focusing electron beams on a sample 17 is provided between focusing lenses 13, 14 and an objective lens 16.
