Abstract: High-speed and high-accuracy focus adjustment is achieved. A microscope system (1) includes: an irradiation unit (18) that emits line illumination parallel to a first direction; a stage (26) that supports a specimen and is movable in a second direction perpendicular to the first direction; a phase difference acquisition unit (60I) that acquires phase difference information regarding an image of light emitted from the specimen by being irradiated with the line illumination; an objective lens (22) that focuses the line illumination on the specimen; a derivation unit (60E) that derives relative position information between the objective lens and the specimen based on the phase difference information; and a movement control unit (60F) that causes at least one of the objective lens and the stage to move in a third direction vertical to each of the first direction and the second direction based on the relative position information.

Abstract: A microscope system includes: a light source unit that emits linear illumination parallel to a first direction; an objective lens that condenses the linear illumination onto a measurement target region; an acquisition unit that acquires a first optical signal indicating a light intensity value of light emitted from the measurement target region by the linear illumination; and a focus control unit that controls at least one of a relative position or a relative posture of the light source unit and an imaging unit that generates the first optical signal on a basis of a light intensity distribution of the first optical signal.
