ABSTRACT:
An eyeball microscope used for observing or photographing epithelial and endothelial cells and likes of a cornea, which is provided with an illuminating optical system for projecting an illuminating light beam onto an object, an observing optical system for observing or photographing an imaging light beam from the object and parallel slits moving across the optical paths of both optical systems, and arranged to scan the object with optical images of some of the slits and observe imaging beams from the object through other slits, thereby shutting off all unwanted reflecting beams. In this invention, it is suited for both eye observation and photography by composing the slits of plural groups which are mutually different in design.
