Abstract
A microscope apparatus including an illumination apparatus capable of, regardless of the observation magnification of an imaging optical system, filling the entrance pupil of the imaging optical system with illumination light, and suitably restricting the conjugate image of the entrance pupil of the imaging optical system by a light shielding element. A microscope apparatus is configured by including: an illumination apparatus which includes a surface light emitter (light guide plate) having a light emitting surface as a planar light-emitting region and irradiates a sample with light emitted from the light guide plate; an objective lens which condenses light from the sample; and an imaging optical system which includes a variable power lens group configured to form an image of the sample by changing the magnification of the image of the sample. The illumination apparatus includes a light shielding plate and a light diffusing element.
