ABSTRACT:
An apparatus for viewing a region within a body cavity or the like. The apparatus includes an elongate light pipe having a distal end and a proximal end, which light pipe illuminates the region to be viewed adjacent the distal end of the pipe. An objective lens system is carried at that distal end which in a preferred embodiment forms a focused real image of the illuminated region. This image is transmitted to the viewer through a series of relay lenses and, at the proximal end of the apparatus, through a viewing lens system. The light pipe and the lenses are composed of a polymeric material such as styrene, polycarbonate, acrylic, or the like, and are preferably aspheric lenses.
