Abstract

Provided is a driving control method of an objective lens in which an optical-axis chromatic aberration can be corrected by driving the objective lens, and an image can be quickly captured by realizing a quick driving and stabilizing of the objective lens so as to acquire a three-dimensional image at a high speed. A driving control method of the objective lens driven by a piezoelectric actuator provided in a fluorescence microscope includes a first step of applying a pulse voltage larger than a displacement voltage making the objective lens move to a focal position of an observation target to the piezoelectric actuator for a predetermined time so as to move the objective lens near the focal position, and a second step of applying the displacement voltage to the piezoelectric actuator after the first step to stabilize the objective lens.
