ABSTRACT:
A fluorescent microscope comprises a light source, an optical illumination system which forms an optical path to irradiate a specimen with a light beam from the light source, an objective lens which condenses the light beam of the optical illumination system onto the specimen, an optical device which is disposed on the optical path of the optical illumination system and which decenters the light beam by decentering an optical axis of the optical path, and a slit which passes the light beam decentered by the optical device through a total reflection illumination region on an emission pupil surface of the objective lens.
