Abstract: A microscope includes a stage on which a specimen is configured to be placed, an epi-illumination optical system having a fluorescence illumination light source configured to irradiate the specimen with excitation light of a predetermined wavelength, a transmitted-light illumination optical system, and a light shielding member. The transmitted-light illumination optical system includes a transmitted-light illumination light source having a white LED, and a condenser having a condenser lens configured to collect light emitted from the transmitted-light illumination light source onto the specimen and configured to move in a direction orthogonal to an illumination optical path so as to be insertable onto and removable from the illumination optical path. The light shielding member is configured to move in the direction orthogonal to the illumination optical path along with the condenser lens to block incidence of the excitation light from the epi-illumination optical system to the transmitted-light illumination optical system.
