The Ball lenses always are manufactured from a single substrate of glass. It is able to focus or collimate light, depending upon the geometry of the input source. The Ball lenses are used for improving the coupling between optical fibers and the emitters or detectors. They are also used in endoscopy, bar code scanning, ball pre-forms for Aspheric lenses and sensor applications.
