An adapter system connects a smart-phone or other camera to an ophthalmoscope or other viewing instrument at multiple locations with a single bracket. A fitting attached to the bracket connects the adapter to the viewing instrument in the region near its view port, close to the optical axis. A brace attached to the bracket connects the adapter to the viewing instrument in the region of the instruments handle or other support structure, located away from the optical axis. The brace has a frame that holds the camera in place and aligns the camera lens with the optical axis of the instrument. The processor of the smart-phone or other mobile communications device can provide specific information related to the particular viewing instrument and can also be used in the operation and control of smart-scope instruments through a communications link.
