    Abstract: A microscope apparatus 10 includes a detection optical system 12 that captures light from a sample S and an illumination optical system 11 that radiates an illumination light onto the sample S. The illumination optical system 11 includes a cylindrical lens 5 that has a power in a first-axis direction and does not have a power in a second-axis direction that is perpendicular to the first-axis direction, a cylindrical lens 6 that has a power in the second-axis direction and does not have a power in the first-axis direction, and a scanner 4 that scans the illumination light in a width direction. The illumination optical system 11 is configured such that the first-axis direction is the width direction described above, and the cylindrical lenses 5 and 6 are arranged posterior to the scanner 4.

    Abstract: For achieving an expanded observation range without sacrificing resolution, a scanning optical system according to the present invention includes a scanner that deflects laser light from a light source while changing a deflection angle of the laser light; a polarization beam splitter that is capable of splitting-off the laser light from an optical path of the laser light deflected by the scanner; a polarization beam splitter that is disposed between the light source and the scanner and that causes the laser light split-off by the polarization beam splitter to travel toward the scanner; and a first relay optical system that has 1× relay magnifying power and that is disposed between the polarization beam splitter and the polarization beam splitter. The first relay optical system relays the laser light split-off by the polarization beam splitter so as to cause the laser light to be incident again on the scanner at the same position as an incident position of the laser light from the light source via the polarization beam splitter.
