Claim:
1. A microscope apparatus comprising: a light source configured to emit a coherent illumination light; an optical system configured to irradiate a specimen with the illumination light; and a detector configured to form an image based on a light generated from the specimen by the illumination light that irradiates the specimen, wherein the optical system includes: a pinhole array that includes a plurality of pinholes and generates a plurality of illumination lights by passing the illumination light from the light source through the pinhole array; a condenser lens configured to project the plurality of illumination lights having passed through the pinhole array on the specimen as a plurality of focal points; and a phase plate positioned to oppose to the condenser lens with the specimen interposed therebetween and configured to shift a phase of transmitted light that has passed through the specimen and a phase of a diffracted light that has been diffracted by the specimen to be deviated from each other by a predetermined wavelength, and the detector is configured to generate a contrast by interference of the transmitted light and the diffracted light that have experienced phase shift by the phase plate.
