Abstract: A light sheet microscope includes an objective, an illumination optical system, a first adjustor, a second adjustor and a controller. The illumination optical system irradiates sample with a light sheet from a direction that is different from an optical axis direction of the objective. The first adjustor adjusts a relative position between a light sheet plane on which the light sheet is formed and the objective in an optical axis direction of the objective. The second adjustor adjusts a relative position between the light sheet plane and the sample in an optical axis direction of the objective. The controller controls the first adjustor on the basis of light that is from the light sheet plane and that is detected via the objective when a relative position between the light sheet plane and the sample is changed by the second adjustor.

Abstract: The present invention provides a light-field microscope including: an illumination optical system that radiates excitation light onto a sample; and a detection optical system including an objective lens that collects fluorescence generated in the sample as a result of the sample being irradiated with the excitation light by the illumination optical system, an image-acquisition element that acquires an image of the fluorescence collected by the objective lens, and a microlens array disposed between the image-acquisition element and the objective lens. The illumination optical system radiates a beam of the excitation light having a predetermined width in the optical-axis direction of the objective lens so as to include the focal plane of the objective lens onto the sample in a direction substantially perpendicular to the optical axis.

Abstract: A laser microscope includes an objective lens that radiates a laser beam onto a specimen; a stimulation optical system having an LCOS-SLM located at a position optically conjugate with the pupil position of the objective lens and which modulates the phase of the laser beam; and an observation optical system having a galvanometer mirror that scans the laser beam across the specimen, as observation illuminating light, and a PMT that detects the observation light coming from the specimen and collected by the objective lens. A control unit forms a three-dimensional image of the specimen and sets, in that image, stimulation sites in the specimen to be irradiated with a laser beam serving as a stimulation beam by the stimulation optical system at a plurality of different positions in the optical axis direction. The LCOS-SLM modulates the laser beam such that the stimulation sites are irradiated with the laser beam.
