ABSTRACT:
An ophthalmoscope for observing the fundus of an eye includes a casing, a light source for illuminating the fundus, lens means for viewing the illuminating fundus, electrical energy producing means for providing electrical energy to the light source and means electrically connecting the electrical energy producing means and the light source, the electrical energy producing means being supported on, extending substantially completely around and substantially conforming to the outer surface of the casing. Desirably, the electrical energy producing means is a battery having at least one battery section, each battery section including at least two substantially annular contact members and a plurality of battery cells arranged in spaced relation and disposed between and electrically connected to the contact members. The cells within each battery section are electrically connected in parallel and adjacent battery sections are electrically connected in series.
