ABSTRACT:
A relay lens assembly and a method for manufacturing a relay lens system for an endoscope includes the steps of providing at least one rod member having first and second curved end surfaces, positioning a mold surface at a predetermined distance from one of the curved end surfaces of the rod member wherein the mold surface has a profile which is the negative of a required optical profile to be formed on the curved end surface, filling a space defined by the predetermined distance between the mold surface and the curved end surface with a moldable light transmissive material and solidifying the moldable material to form a molded layer adhered to the curved end surface.
