An optical device and microscope of simple construction and which is capable of readily attaining super resolution with good focusing performance, includes a light source that generates light of multiple different wavelengths, a focusing optical device that focuses lights of these multiple wavelengths on an object, and an emitted light detector that detects light emitted from the object. Among the multiple lights of different wavelengths generated from the light source, at least one light forms a condensed light pattern of multiple spatial modes. These multiple lights are condensed upon the object such that part of the region of the condensed light pattern of the multiple spatial modes is made to spatially overlap with the condensed light pattern of the other light.
