Abstract: There are provided a microparticle measuring device capable of analyzing microparticles with increased accuracy and a microparticle analysis method. According to a microparticle measuring device 1, transmission images of microparticles in the liquid sample are captured by a plurality of image capturing units that are disposed in mutually different orientations with respect to a liquid feed pipe when viewed in a cross section orthogonal to the flowing direction of a liquid sample in the liquid feed pipe, and the microparticles are analyzed by an analyzing unit on the basis of the transmission images.

Abstract: Provided is a microscope device which includes: (1) a light source that outputs illumination light in a wavelength band including a near-infrared region; (2) an illumination optical system that irradiates an observation target with the illumination light output from the light source; (3) an image formation optical system that includes a spectroscopic unit which is configured to receive and disperse transmitted or scattered light produced at the observation target by irradiating the observation target with the illumination light, and that forms an image on the basis of the dispersed transmitted or scattered light; and (4) an image capturing unit that acquires the image formed by the image formation optical system. An illumination-light-irradiated area of the observation target is larger than an area of the field of view of the image formation optical system, and is less than or equal to ten times the area of the field of view.

Abstract: A microscope that makes it possible to acquire a hyperspectral image with high data precision includes a light source, an illumination optical system, an image-forming optical system, an imaging unit, a spectroscope, a stage, a drive unit, and a control unit. The illumination optical system converges, at a converging angle θ, illuminating light in a wavelength band included in the near-infrared region output from the light source, and emits the converged illuminating light onto the object being observed. The image-forming optical system forms an image based on transmitted and scattered light generated by the observed object by emission of the illuminating light onto the observed object. The sin θ is set to a value that does not exceed the numerical aperture of an objective lens that receives the transmitted and scattered light from the observed object.
