Abstract
An improved construction for electrically illuminated otoscopes whereby more light is provided and the light is whiter and more uniform than the light output of prior art instruments. To obtain more light, a larger than normal lamp is employed which preferably is a halogen lamp as the latter gives a whiter light than a vacuum lamp and has a longer life span. Since a larger lamp produces more heat and would be more of an obstruction if positioned in the usual location, the lamp is positioned in the base of the instrument and its light is transmitted from there to a point in the viewing passage through the instrument by a bundle of optical fibers. The fiber bundle minimizes viewing passage obstruction and assists in providing the uniform, diffuse illumination that is desired without light loss.
