ABSTRACT:
A disposable endoscope having an object lens assembly, a relay lens assembly, and an imaging lens assembly with at least the relay lens assembly optical elements being made in whole or in part of molded glass lenses. the relay lens assembly preferably consists of molded glass curved surface lenses arranged in triplet lens configuration with ground or molded glass rod lenses disposed between the curved surface lenses. In preferred embodiments the positive lens elements of each triplet assembly may be bonded in optical contact with the rod lenses or the rod lenses may constitute molded glass lenses incorporating the positive lenses of each triplet. Optical components of the objective and imaging lens assemblies may be of molded or ground glass, and illumination may be conducted by glass or plastic fibers.
