Abstract
A highly aligned optical device which includes an optical element with an optical surface to which are attached electrodes in which is installed in a housing which includes a transparent enclosure for defining a lens. The optical element is very carefully aligned in three dimensions within the transparent enclosure lens and the lens surface is specially contoured to optimize the mechanical/optical characteristics of the device. The device may be an emitter in which case the device is instrumental for generating a very narrow collimated beam of LED rays, or a detector with a special lens which receives the narrow beam of LED rays and focuses the beam to fill the optically active area of detectors to maximize and optimize the current transfer ratio between the emitter and the detector over distances.
