Abstract
A drive unitof a surgical microscope apparatusmoves an entire optical system horizontally. A drivermoves a head lensvertically. An imaging devicedetects reflected light (observation light) of illumination light guided by an observation optical system. A controllerobtains a cross-sectional shape of the observation light based on the result of the detection of the observation light by the imaging device, and controls the drive unitto move the optical system horizontally so that this cross-sectional shape becomes a specified reference cross-sectional shape. Moreover, the controllerobtains the luminance distribution of the observation light based on the result of the detection of the observation light by the imaging device, and controls the driverto move the head lensvertically so that this luminance distribution becomes a specified reference distribution profile.
