Abstract

A microscope apparatus includes an illumination optical system that illuminates a sample, an observation optical system that guides light from the sample, and an intensity modulator that is provided in a pupil of the observation optical system or a position optically conjugate with the pupil and reduces light incident on the intensity modulator. The light utilization rate distribution as an intensity transmittance distribution of the intensity modulator in the pupil or in an image of the pupil monotonously increases or monotonously decreases in a first direction. The light utilization rate distribution varies on both sides of a center of an optical axis.
