Telescopic collimator and method of manufacture

摘要

A multi-fiber optical collimator includes a plurality of optical fibers for carrying optical signals, a first lens and a beam expander. The first lens has first and second sides and a first focal length. The first side of the first lens is positioned a distance of about the first focal length from first ends of the optical fibers. The beam expander has first and second sides and the first side of the beam expander is positioned to face the second side of the first lens. The second side of the beam expander provides collimated beams associated with the optical signals carried by the optical fibers.
