Spherical ball lenses are widely used in optical measurement systems, projection & imaging optical systems. Also for laser collimating and focusing, laser-to-fiber coupling, fiber-to-fiber coupling, and fiber-to-detector coupling.
We provide all kinds of ball lens such as ZnS ball lens, fused silica ball lens, MgF2 ball lens and so on.
