Abstract
A microscope illuminating apparatus includes a light-shielding tube surrounding an objective lens, detachably mounted on a revolver of a system microscope in order to guide illumination light to irradiate an observation field, thus separating an illumination optical path and an observation optical path. An annular illuminating section serving as a light source of the illumination light is provided at a position to oppose an end portion aperture of the illumination optical path in the revolver.
