Ball lenses are highly transparent spheres made of optical glasses. They are used to focus light into fibers as in diode laser-to-fiber coupling as well as fiber-to-fiber coupling. They have high coupling efficiency and should be much easier to align than traditional lenses due to their physical shape.
