Microscope system including detachable stage and detachable transmitted illumination optical system

1. A microscope system comprising:

a stage on which a specimen is placed;

an objective lens configured to condense at least observation light from the specimen on the stage;

a transmitted illumination optical system configured to irradiate the specimen with transmitted illumination light ejected from a first light source, which is illumination light transmitting through the specimen, the transmitted illumination optical system including a transmitted illumination and imaging unit which houses a mirror which reflects the transmitted illumination light ejected from the first light source toward the specimen;

a microscope body part including a base unit holding the transmitted illumination optical system including the transmitted illumination and imaging unit which houses the mirror, a supporting column standing upright from the base unit, and an incident-light illumination optical system provided on an end of the supporting column on a side different from a base unit side of the supporting column and irradiating the specimen with incident-light illumination light which is illumination light ejected from a second light source to be reflected on the specimen; and

an objective arm provided on the supporting column, the objective arm supporting a revolver holding the objective lens, and being elevatable along the supporting column,

wherein the stage and the transmitted illumination optical system including the transmitted illumination and imaging unit which houses the mirror are attachable to and detachable from the microscope body part, and

wherein the specimen is placeable on the base unit in a state in which the stage and the transmitted illumination optical system are separated from the microscope body part.

2. The microscope system according to claim 1 ,

wherein the transmitted illumination optical system further includes a condenser.

3. A microscope system comprising:

a stage on which a specimen is placed;

an objective lens configured to condense at least observation light from the specimen on the stage;

a transmitted illumination optical system configured to irradiate the specimen with transmitted illumination light ejected from a first light source, which is illumination light transmitting through the specimen; and

a microscope body part including a base unit holding the transmitted illumination optical system, a supporting column standing upright from the base unit, and an incident-light illumination optical system provided on an end of the supporting column on a side different from a base unit side of the supporting column and irradiating the specimen with incident-light illumination light which is illumination light ejected from a second light source to be reflected on the specimen,

wherein the stage and the transmitted illumination optical system are attachable to and detachable from the microscope body part,

wherein the microscope body part comprises:

an elevation unit provided on the supporting column, the elevation unit supporting the stage in a detachable manner, and being elevatable along the supporting column, and

a placement member which is attachable to the elevation unit in a state in which the stage and the transmitted illumination optical system are separated from the microscope body part, and

wherein the placement member places the specimen in an installation region of the transmitted illumination optical system.

4. The microscope system according to claim 3 , wherein the transmitted illumination optical system includes a condenser, and the elevation unit attachably and detachably supports the condenser.
