Abstract
An observation laser beam for observing a specimen and a manipulation laser beam for manipulating the specimen are multiplexed; the multiplexed beams irradiate the specimen, which is mounted on a stage, via an objective lens; and fluorescence emitted from inside the specimen in the observation optical axis direction is detected. In a preparation mode, a focal-position adjusting unit is controlled so that the focal position of the observation laser beam and the focal position of the manipulation laser beam are coincident, independent of the movement of the objective lens or the stage by a focusing mechanism; and in an observation mode, the focal-position adjusting unit is controlled so as to cancel out the shift of the focal position of the manipulation laser beam according to the movement of the objective lens or the stage.
