Motorized correction collar system, method of correction collar calibration performed by motorized correction collar system, and computer readable medium

A method of adjusting a correction collar ring of an objective lens performed by a motorized correction collar system that includes the objective lens, the method comprising:

• acquiring calibration information corresponding to the objective lens from calibration information stored for each of one or more types of objective lenses with correction collar rings, the calibration information comprising respective misalignment amounts between correction collar positions of the correction collar rings that correspond to a reference position of a transmission mechanism of the motorized correction collar system and correction collar positions of the correction collar rings that correspond to origin positions of the correction collar rings;
• controlling a drive mechanism of the motorized correction collar system to rotate the correction collar ring of the objective lens until a sensor of the motorized correction collar system detects the reference position of the transmission mechanism;
• and
• controlling the drive mechanism to rotate the correction collar ring of the objective lens by a misalignment amount based on the calibration information corresponding to the objective lens.

A non-transitory computer-readable medium storing instructions that, when executed by at least one processor, cause a motorized correction collar system to:

• acquire calibration information corresponding to an objective lens of the motorized correction collar system from calibration information stored for each of one or more types of objective lenses with correction collar rings, the calibration information comprising respective misalignment amounts between correction collar positions of the correction collar rings that correspond to a reference position of a transmission mechanism of the motorized correction collar system and correction collar positions of the correction collar rings that correspond to origin positions of the correction collar rings;
• control a drive mechanism of the motorized correction collar system to rotate a correction collar ring of the objective lens until a sensor of the motorized correction collar system detects the reference position of the transmission mechanism;
• and
• control the drive mechanism to rotate the correction collar ring by a misalignment amount based on the calibration information corresponding to the objective lens.
