IPC: G02B21/26
Filed: 1997-12-29
Abstract: PROBLEM TO BE SOLVED: To prevent the desired place of a sample from going out of the visual field of an aperture at the time of changing the angle of the aperture. SOLUTION: A deviating amount between a central axis 43 at the time of rotating an aperture holder 31 and the center of aperture part 36 is previously measured and correcting data are stored in a memory 28 attached to a deviating amount calculating part 27. When an operator instructs the change of an angle, a rotation control part 22 rotates a motor 21 according to the changing amount to the angle. At the same time, the deviating amount calculating part 27 calculates the shifted amount of the position from the angle after rotation and sends it to a horizontal movement control part 28. The horizontal movement control part 26 controls motors 24, 25 for moving a stage 41 in the directions of X and Y axes according to the shifted amount of the position.  Consequently, even when the angle is adjusted, the position of a sample 44 is automatically adjusted so that a sample place located at the center of the aperture part 36 is not moved.
