Solid color marbles are highly polished sphere of optically transparent homogeneous material. Carefully controlled manufacturing processes produce spheres with precise diameters and unrivaled surface quality. Spherical ball lenses are commonly used for laser collimation and focusing, laser-to-fiber coupling, fiber-to-fiber coupling, and fiber-to-detector coupling. Larger spheres are easier to handle and reduce the sensitivity of translational alignment. However, smaller spheres have the advantage of being suitable for smaller packages. Hemispherical (hemispherical) lenses are ideal for applications such as fiber optic communications, endoscopes, microscopes, optical pickup devices, and laser measurement systems.
