Ball Lens
Ball Lenses provide for a shorter back focal length, simplifying fiber coupling, due to the
high index of refraction. Ball lenses are manufactured from a single glass substrate and can
either focus or collimate light. Ball Lenses are ideal for endoscopy, bar code scanning, ball
pre-forms for aspheric lenses, and sensor applications.
