A microscope includes: an objective lens having an optical system; a correction collar provided on the objective lens and configured to move the optical system in a direction of an optical axis of the optical system by rotating around the objective lens to correct aberration; a switching unit to which the objective lens is attachable and which switches a position of the objective lens; a supporting unit for supporting the switching unit; and a focusing unit that holds the supporting unit such that the supporting unit is movable along the optical axis of the objective lens. A correction collar operating device is detachably attached to the supporting unit and includes: an input unit for inputting rotary force to rotate the correction collar; and a correction collar driving unit for rotating the correction collar according to the rotary force while the correction collar driving unit has contact with the correction collar.

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.

An inverted microscope includes: an epifluorescence illumination optical system configured to irradiate a specimen on a stage with epi-illumination light from below the stage; a transmitting illumination optical system configured to irradiate the specimen on the stage with transmitting illumination light from above the stage; an objective lens arranged below the stage and configured to collect the epi-illumination light on the specimen; and a light blocking unit configured to be arranged between the stage and the transmitting illumination optical system so as to be located on or deviated from an observation optical axis of the inverted microscope, and configured to be located at a light blocking position separated from the stage so as to block all direct light entering the objective lens at an angle not larger than an aperture angle of the objective lens.
