Ball lens is a simple lens with very low spherical aberration,so it can converge and collimate light beam exactly.It's characterized by high coupling efficiency,which make it ideal optical components for laser-to-fiber,fiber-to-fiber,and fiber-to-detector coupling.Furthermore,Half-lenses can replace full-ball lenses with a similar optical performance if the physical space is limited.
