Means for scanning a specimen through the objective lens to light from a light source which has passed through the confocal pattern, confocal microscopy, a photoelectric conversion means light from the sample transmitted through the confocal pattern through the objective lens A between the confocal optical system for obtaining the image confocal is focused on, and said objective lens and said light source is disposed at a position conjugate with the pupil position of the objective lens or the pupil position of the objective lens, light I provided, and a variable aperture to allow variable sectioning effect in the axial direction.
