Product Description

   Optical ball lens and half ball lens:Why use a  ball and a half ball lens?

Ball lenses are 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. Half-ball lenses are also common and can be interchanged with full ball lenses if the physical constraints of an application require a more compact design.

        Notes:

 

  • We will process as the drawings and requirements rigorously.
  • Our engineer will check or design the drawings according to the details.
  • In addition,we have some stock lenses for your option.

Half-ball (hemispherical) lenses are ideal for applications such as fiber communication, endoscope, microscopy, optical pick-up devices, and laser measurement systems.
