ABSTRACT:
A confocal microscope uses fluorescent or reflected light obtained by irradiating a plurality of beam spots to a sample so as to observe the sample. The confocal microscope has a phase modulator element which modulates phase of laser light to form the beam spots, a liquid crystal element which forms a plurality of pinholes through which only the fluorescent or the reflected light is transmitted, and a control section which controls the phase modulator element and the liquid crystal element.
