Glass ball lens 

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 fit into smaller packages. Coupling efficiency is generally >*0% due to the simplicity of these lenses.
