Abstract: An imaging system includes: an imaging apparatus that includes an image sensor and acquires a captured image; an optical system that includes a first objective and forms, within the image sensor, an optical image of a visual-field region that is a region within an object surface that corresponds to the objective field number (OFN) of the first objective; a motorized stage; and a control apparatus that constructs a first wide region image by piecing together a plurality of constituent images included in a plurality of captured images acquired by controlling the motorized stage and the imaging apparatus, the first wide region image being an image of a region wider than the visual-field region. Each of the plurality of constituent images is a portion of each of the plurality of captured images and is also at least a portion of each of images of a plurality of visual-field regions.

Abstract: A microscope adapter unit disposed on an optical path of illumination light between a light source unit including a light source and a sample surface includes a first lens group having at least one lens and a second lens group having at least one lens. The first lens group converts the illumination light into roughly parallel luminous fluxes, and makes the illumination light enter the second lens group.

Abstract: A microscope illumination device includes a white LED light source, and an illumination optical system that includes an aperture stop on a plane on which light from the white LED light source is condensed. The white LED light source includes a board, a plurality of LED chips that are arranged on the board and that each emit excitation light, and a phosphor layer that is provided so as to cover the plurality of LED chips and that includes at least three types of phosphors. The plurality of LED chips are arranged so as to be projected into an aperture of the aperture stop.
