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. Coupling efficiency is generally >90% due to the simplicity of these lenses. For this spherical ball lenses we can make them from all of the glass material.
