ABSTRACT:
An optical-path switching apparatus for an optical microscope, which is simple structure, has a plurality of optical devices to be inserted and removed to and from at least two or more switching positions provided for optical paths so as to switch the optical paths. A drive force generator generates a drive force, and an insertion/removal device transmits the drive force generated by the drive force generator so as to insert and remove the plural optical devices to and from the switching positions while relating the plural optical devices to one another. A control unit controls switching of the optical devices to be performed by the insertion/removal device in order to obtain a required optical path.
