Abstract: An optical microscope includes a light source which irradiates a sample with illuminating light. A mirror, which has a variable reflection surface, reflects the illuminating light. A correction table stores plural data of plural shapes of the reflection surface which correspond to changes in a focal position and an aberration. A controller selects, from the plural data stored in the correction table, data of one of the shapes of the reflection surface that is suitable for correcting the focal position and the aberration. And the controller controls the mirror so that the reflection surface forms the shape corresponding to the selected data.

Abstract: Provided is a laser scanning microscope having a first focusing-position control unit; and a confocal detecting unit. The first focusing-position control unit shifts a first focusing position of a laser beam on a sample in a direction of an optical axis of an objective lens. The confocal detecting unit has a confocal aperture for a confocal detection of a light emitted from the first focusing position. The microscope may include a second focusing-position control unit shifts a second focusing position of the light emitted from the first focusing position focused by the confocal detecting unit in a direction of an optical path thereof.
