<p>To provide a microscope apparatus including an illumination apparatus which is 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 1 is configured by including: an illumination apparatus 2 which includes a surface light emitter (light guide plate 21) having a light emitting surface as a planar light-emitting region and irradiates a sample S with light emitted from the light guide plate 21; an objective lens 31 which condenses light from the sample S; and an imaging optical system 3 which includes a variable power lens group 32 configured to form an image of the sample S by changing the magnification of the image of the sample S. In the microscope apparatus 1, the illumination apparatus 2 includes a light shielding plate 22, as a light shielding element, which is arranged on the sample side of the light emitting surface of the light guide plate 21 and shields a part of a luminous flux emitted from the light emitting surface, and a light diffusing element 23 which is arranged on the sample side of the light shielding plate 22 and diffuses light from the light guide plate 21.</p> |
