Abstract
There is disclosed a microscope provided with a parallel ray optical system, for forming parallel light rays, between the objective lens and the eyepiece lens. A lens barrel supporting the parallel ray optical system is axially extended or retracted with respect to the objective lens, such as by mutual engagement of a ratchet and a claw member, thereby varying the optical path length of the parallel light rays and thus adjusting the height of the eyepiece lens.
