Abstract
A headlamp module for providing a uniform field of illumination at a predetermined distance includes a headlamp housing having a first end and a second end. A light source such as a terminated fiber optic cable is disposed within the first end of the housing. A condenser system is disposed within said headlamp housing in optical communication with a light source which is positioned close to the condenser. The condenser system, which comprises a pair of planar convex lenses oriented with the convex sides facing each other, is in optical communication with a reflecting element such as a planar mirror or a reflecting prism. The light reflected by the reflecting element is directed to an exit lens, such as a projection lens or an objective. The light exiting the exit lens provides the uniform field of illumination despite the presence of a real image of the light source termination at a distance close to the exit lens. An iris may be used between the condenser and the reflective element to narrow the light reaching the reflective element.
