Ball Lens For Sports Cameras

Ball Lens For Sports Cameras Ball lenses are commonly used for laser collimating and focusing, laser-to-fiber coupling, fiber-to-fiber coupling, Solar-photovoltaic and fiber-to-detector coupling. Worldhawk can provide spherical ball lenses and half ball lenses in a range of substrates for performance in the ultraviolet to the NIR. Such as including H-K9L(N-BK7), Sapphire, CaF2, BaF2, ZnSe or custom materials upon request. Ball lenses feature short back focal lengths to minimize the distance needed from the ball Lens to the optical fiber. Ball lenses are commonly used to improve signal quality in fiber coupling applications, or for use in endoscopy or bar code scanning applications.   Specifications of Ball Lens (Half ball lens)    Item    Parameter (Optical glass ball lens; Half ball lens)   Material   K9 (BK7), Optical sapphire(ruby) glass, fused silica, JGS1,   ZnSe,  Zns, Ge, Caf2, b270, LaF52, Schott glass   Diameter   1~150mm, 1mm, 2mm, 3mm…   Dia.
