Abstract
An illumination optical system includes: a beam splitter located near a conjugate position of a specimen and configured to split beams from a light source into a plurality of groups of beams having different splitting directions around an optical axis; a beam selector configured to select and transmit one group of beams from the plurality of groups of beams and that is rotatable with respect to the optical axis; and a ½ wavelength plate located near the beam selector and rotatable about the optical axis. The rotation angles of the ½ wavelength plate and of the beam selector about the optical axis are respectively set so that the polarization direction of the beam which has passed through the ½ wavelength plate is perpendicular to the splitting direction of the one group of beams that has been selected by the beam selector and split by the beam splitter.
