Abstract
An optical system to be incorporated in endoscopic instrumentation is provided. The optical system includes objective lens, relay lens and eye lens assemblies. The objective and eye lens assemblies are comprised of a plurality of axially aligned polymeric lenses. The relay lens assembly includes at least one relay lens module for transferring an image between successive image planes. The relay lens module consists of two identical optical assemblies arranged in bilateral symmetrical relation relative to a median plane. Each optical assembly includes a glass plano cylinder and polymeric curved lenses. The physical and geometrical characteristics of the components are selected to effectively transfer a bright image to the viewer.
