BALL LENS
Ball lenses are near perfect polished spheres of glass or other transparent materials used to focus light from laser sources into fibers and to couple light from fiber to fiber by matching the N.A.(numerical aperture) of the balls to the fibers.Balls can be machined into drums for higher fiber array pitch and mounting alignment accuracy.
