Znse Optical Ball Lens are widely used in Laser Machine. Optical Balls is a great optical components for improving signal coupling between fibers, emitters, and detectors. They are also used in endoscopy, bar code scanning, ball Pre-forms for aspheric lenses, and sensor applications. Ball lenses are manufactured from a single substrate of glass and can focus or collimate light, depending upon the geometry of the input source. tages than silicone lens and plastic lenses.
