Abstract: A microscope apparatus 10 includes a detection optical system 12 that captures light from a sample S and an illumination optical system 11 that radiates an illumination light onto the sample S. The illumination optical system 11 includes a cylindrical lens 5 that has a power in a first-axis direction and does not have a power in a second-axis direction that is perpendicular to the first-axis direction, a cylindrical lens 6 that has a power in the second-axis direction and does not have a power in the first-axis direction, and a scanner 4 that scans the illumination light in a width direction. The illumination optical system 11 is configured such that the first-axis direction is the width direction described above, and the cylindrical lenses 5 and 6 are arranged posterior to the scanner 4.

Abstract: In the present invention, cells cultured inside the wells of a microplate are observed easily and clearly regardless of the height or curvature state of the liquid surface of the culturing liquid. Provided is an observation device that includes an illumination optical system that irradiates a transparent sample with illumination light from a light source, an objective lens that collects observation light from the sample, a detection optical system that detects the observation light collected by the objective lens, and a retroreflective member that is arranged opposite the objective lens with the sample interposed therebetween and in which a plurality of very small reflective elements are arrayed. The objective lens and the illumination optical system are arranged below the sample in the direction of gravity.

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.
