A laser beam from a light source is reflected by a beam splitter and two galvanomirrors, and enters a pupil projection lens. The beam passing through the lens forms a spot on an image plane of an objective. This spot is two-dimensionally scanned by shaking the galvanomirrors with respect to their axes perpendicular to each other. Reflected light or fluorescence from a sample is returned to the beam splitter through the same path, passes through it, and is then reflected by a mirror. This optical system includes an optical unit which can be inserted/removed therein/therefrom. When the optical unit is removed, the optical system serves as a confocal optical system. When the optical unit is inserted, the optical system serves as a nonconfocal optical system. In the confocal optical system, the beam from the mirror enters a condenser, converges, passes through an iris and enters a photomultiplier tuber. The condenser includes a convex lens and a concave lens. In the nonconfocal optical system, the beam from the mirror enters a condenser, converges and is focused on the iris to a spot. The beam passing through the iris enters the photomultiplier tube.
