Abstract
A motorized correction collar system includes: an attachment portion; a control unit that controls transmission of force to a correction collar ring of a first objective lens attached to the attachment portion; and a storage unit that stores calibration information at least for each type of objective lens with a correction collar. The control unit acquires calibration information corresponding to the first objective lens from among the calibration information stored in the storage unit, and calibrates the correction collar of the first objective lens based on the calibration information.
