ABSTRACT:
A confocal microscope comprises a light source emitting a polarized light beam, an objective lens irradiating the polarized light beam, which is deflected and scanned by the optical scanner, to the sample as an excitation light beam, a wavelength separator detecting a necessary wavelength band from a polarized fluorescence emitted from the sample which is excited by the polarized light beam, and a photodetector unit having a polarization property extractor extracting a fluorescence with a predetermined polarization property from the fluorescence detected with the wavelength separator, a wavelength selector selecting a wavelength of the fluorescence extracted by the polarization property extractor, and a photodetector detecting the fluorescence selected by the wavelength selector.
