Patent ID: 8411358

Claim:
A microscope apparatus comprising: a first stimulation optical system including a galvanometer mirror that scans first stimulus light on a specimen to apply optical stimulus to the specimen; a second stimulation optical system including a spatial light modulator that selectively switches an irradiation position of second stimulus light on the specimen to apply optical stimulus to the specimen; a stimulation light-path combining section that combines a light path of the first stimulation optical system and a light path of the second stimulation optical system; an observation optical system which acquires an image of the specimen, the observation optical system including a light source that illuminates the specimen, a scanning unit that scans illumination light on the specimen, and a photoelectric conversion device that receives light emitted from the specimen; and a whole-light path combining section that combines a light path of the observation optical system with the light paths of the first stimulation optical system and the second stimulation optical system combined by the stimulation light-path combining section.
