Half Ball Lens

Ball lens is used to improve the signal coupling between optical fiber, transmitter and detector, improve the signal quality, and can also be used in endoscopy, bar code scanning, aspherical lens preprocessed materials, sensors, etc. The ball lens has a short focal length, which minimizes the distance needed to travel from the ball lens to the fiber. Ball lens commonly used in the optical fiber coupling, laser collimating device, Optical Measurement System, it has a shorter focal length and the characteristics of small size. Sunday produce ball lens, half ball lens, Super hemisphere ball lens, hollow ball lens.Sunday Optics can manufacture ball lens Minumum diameter 0.3mm.
