ABSTRACT:
A confocal microscope with improved light use efficiency is provided. Thus, the confocal microscope has a section which concentrates illumination light to a target point of a specimen and non-target points adjacent thereto for simultaneous illumination; a section which receives light entering into a light reception portion conjugated with the target point, without distinguishing light emitted from the target point and light emitted from the non-target points, and outputs a light reception signal according to the intensity of the light; a section which changes the number of non-target points and successively captures the light reception signals before and after the change in the number of the target points; and a section which generates a confocal signal according to intensity of light emitted from the target point, based on a relationship between the captured light reception signals and the number of non-target points.
