half ball lens.mp4

Fused silica half ball lens has a high transmittance between 200nm and 2.2μm and a low thermal expansion coefficient, making it an ideal choice for demanding ball lenses in ultraviolet, visible and near-infrared spectroscopy applications.Ball lenses can collimate light  and focus light. 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 lenses are made of a single glass substrate and can focus or output parallel light, depending on the geometry of the input source.
