ABSTRACT:
A relay lens system to be incorporated in an endoscopic optical assembly is provided. The relay lens system includes at least one relay lens module for relaying 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 disposed between the two assemblies. Each optical assembly includes a glass plano cylinder and first and second curved lens components attached to each end of the plano cylinder. The lenses forming the lens components are fabricated from different optical materials including polymeric materials to correct aberrations within the system. The physical and geometrical characteristics of the components are selected to effectively transfer a bright image to the viewer.
