Abstract: A light sheet microscope includes an objective, an illumination optical system, a correction device, an image pickup device, a first adjustor, a second adjustor and a controller. The controller performs a first focus process and a spherical aberration correction process. The first focus process is a process in which the first adjustor is controlled on the basis of light that is from the light sheet plane and that is detected via the objective so that the light sheet plane and a focal plane become closer when a relative position between the light sheet plane and a sample has been changed. The spherical aberration correction process is a process in which the correction device is controlled so that an evaluation value of the image obtained by the image pickup device becomes greater when the first adjustor has changed the relative position between the light sheet plane and the objective.

Abstract: An observation device includes: an illumination optical system that irradiates illumination light onto a sample, an objective optical system that has a phase modulation region and a light blocking region and that acquires an image of the illumination light transmitted through the sample, and an autofocus mechanism. The objective optical system selectively outputs the illumination light from a first output region disposed at a position where the illumination light is to be projected onto the phase modulation region and a second output region disposed at a position where a portion of the illumination light is to be projected onto the light blocking region. The autofocus mechanism causes the objective optical system to acquire an image of the illumination light while causing the illumination light to be output from the second output region, and detects the focus position of the objective optical system based on the contrast of the acquired image.
