Optical glass N-BK7 ball lenses 

The ball lens is a very useful optical element used to improve the signal coupling between the fiber, the transmitter and the detector. In addition, it is also suitable for applications such as endoscopy, barcode scanning, aspheric lens processing materials and sensors. The ball lens is made of a single glass substrate and can focus or output parallel light, depending on the geometry of the input source.
