Field of view converter for fiber-optic connector endface inspector

摘要

An adapter for converting the field of view (FOV) of a connector endface inspector includes a housing with a front end for connecting with a fitting tip for interfacing with a fiber-optic connector, a rear end for connecting to a front portion of the inspector, and an internal light passage. A relay lens system including a front lens group and a rear lens group is embedded inside the housing across the light passage. To achieve a converted FOV, the optical working distance of the relay lens system is made the same as the optical working distance of the connector inspector's microscope objective, and the front focal length is made larger or smaller than the rear focal length of the relay lens system. The rear lens group may be embedded in a portion of the housing that may be detached and replaced to vary the size of the converted FOV.
