        Optical Ball Lens

        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(NBK7), 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.
