Abstract
A telecentric optical fiber connector, wherein light from an optical fiber is emitted from the connector lens in a comparatively large diameter parallel beam, includes two primary components: an integral optical quality plastic connector body having an annular planar reference surface substantially perpendicular to an optical axis. A convex lens surface is molded, recessed inward from the reference surface. The body is substantially cylindrical, with exterior means thereabout so that it can be engaged with a similar body. The opposite axial end of the body has a central cylindrical cavity therein which extends to a point which is one focal length from the lens surface. A fiber holder, which holds an optical fiber centrally within an axial hole, abuts an end of the fiber against the point one focal length from the lens surface, and can be engaged with index-matching material.
