ABSTRACT:
A combined collimator/diopter cell subassembly for use in a monocular optical device. The subassembly has its own housing, wherein the subassembly housing is a two part structure that joins together in a clam shell like fashion. The subassembly housing defines a plurality of reliefs that engage and retain the various lens elements that comprise the collimator and the diopter cell. The subassembly housing also defines slots that retain mirrors, creating a folded optical path whereby light enters the collimator and exists the diopter cell. Since the subassembly housing is shaped to hold the various lenses and mirrors in a predetermined relationship, the amount of labor required to both produce the collimator and diopter and position them within the optical deice is greatly reduced.
