Abstract:
A focal position determining method determines a focal position of an objective lens focused on an observed target region in a specimen. The focal position determining method includes measuring any one of the focal position of the objective lens at a near point and the focal position of the objective lens at a far point or both so as to determine the focal position of the objective lens focused on the observed target region based on the measured focal position.
