Optical Ball lens Ball lenses are excellent for fibre coupling as they have very low spherical aberration, so focus and collimate light accurately. Ball lenses are extremely hard and durable. Ball lenses are used for focusing light into small fibres, and for use as emitters and detectors Ball lenses are highly polished spheres made of optically transparent homogeneous materials. Ball Lenses are commonly used for laser collimating and focusing, laser-to-fiber coupling, fiber-to-fiber coupling, and fiber-to-detector coupling. Larger spheres are easier to handle and ease the sensitivity of translational alignment. However, smaller sphere has the benefit of fitting into smaller packages.Polished ball lenses are produced by a mechanical machining process. Due to the high flexibility of the process the ball lenses are increasingly used as pre-forms for the precision molding process. The surface and geometry of each ball lens has an optical quality and can therefore also be used as an optical element.
