A scope adapter for coupling a phone to an endoscope includes a base having a phone receiving portion for receiving and releasably supporting a phone. A first base end and a second base end define extents of a base cavity. A shaft is connected at opposite ends to each of the first and second base ends and spans across the base cavity. A threaded shaft is rotationally supported at opposite ends to the first and second base ends and spans across the base cavity. An endoscope positioned within the cavity is movably disposed along the shaft in each of a first direction and an opposite second direction by axial rotation of the threaded shaft. The endoscope includes a lens aperture that is positioned with respect to the phone receiving portion by displacement of the endoscope in either the first or second directions.
