<p>WIDELY SPACED FIBER OPTIC CONNECTOR An imaging component of unitary construction, molded of a transparent optical plastic, and adapted for use with a companion, preferably similar, component to optically couple optical fibers with one another. The component includes a lens surface arranged about an optical axis therethrough, a reference surface for facilitating mounting and positioning the component, and structure for facilitating receiving and positioning the end of an optical fiber at a fixed distance along the optical axis and behind the focus of the lens surface. The optical structure of the component is such that, when used with another axially spaced by a fixed distance and operating at finite conjugates as a pair, the optical fiber end in each is exactly imaged onto or within the entrance pupil of the other. This permits the axial separation between the two components to be substantially greater than the focal length of their lens surfaces so that, among other things, other components such beamsplitters can be introduced between the pair to perform multiplexing functions.</p> |
