Abstract
An apparatus for use in photographing the eye is conveniently hand-held for true portability and is adaptable for usage in conjunction with that equipment ordinarily available in the ophthalmologist's office. The apparatus includes a support for holding in relatively fixed positions and in a secure manner an indirect lens for forming an image of the area to be photographed, a camera for viewing and photographing such image, an aligning mounting bracket for positioning the viewing sight of an indirect ophthalmoscope in correct optical alignment relative to the support and relative to the optical axis of the camera so as to illuminate the object or area to be viewed, and a beam splitter for directing the image light to the camera and passing illuminating light from the indirect ophthalmoscope to the object.
