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.
Claims6
An eyeball microscope comprising:
- a first lens to be positioned close to an object,
- second and third lenses located in the rear of respective halves of said first lens as viewed from said object,
- rotary light shielding means having a number of substantially parallel slits divided into at least two groups of different design and arranged to traverse an optical axis of said second lens in a conjugate focal plane of said object attributable to said first and second lenses and to traverse an optical axis of said third lens in a conjugate focal plane of said object attributable to said first and third lenses,
- an illuminating optical system including a flash discharge tube for projecting an illuminating light beam onto said object through at least one of said slits of said rotary light shielding means to form an image of said slit on said object,
- an observing optical system for observing or photographing an imaging light beam from said object through at least another slit of said rotary light shielding means belonging to the same group,
- a driving device for rotating said rotary light shielding means to move the slit image on said object normally thereto, and
- means for detecting a selected one of said groups of slits to energize said flash discharge tube.
