Ball-LensesIntroduction:
The ball lens is used to improve the signal coupling between the optical fiber, transmitter and detector, and improve the signal quality. It can also be applied to pre-processing materials such as endoscopes, bar code scanning, aspherical lenses, and sensors. The short focal length of the ball lens minimizes the distance required from the ball lens to the fiber. United Optical Technology provides uncoated spherical lenses with K9 optical glass and UV fused silica as the base. Fused silica for UV applications.
