Home | Ball Lens Specification   Contact Us   Links Ball Lens Spherical Ball Lenses are commonly used for laser collimating and focusing, laser-to-fiber coupling, fiber-to-fiber coupling, and fiber-to-detector coupling. Larger spheres are easier to handle and ease the sensitivity of translational alignment. However, smaller spheres has the benefit of fitting into smaller packages.  The addition of a broadband MgF2 antireflection coating results in a highly efficient lens due to the high refractive index of the glass. Coupling efficiency is generally >90% due to the simplicity of these lenses. Red Optronics can supply spherical ball lenses in various materials, including BK7(Glass), Sapphire, CaF2, BaF2, YAlO3, or custom materials upon request.
