Ball lenses are generally used for laser alignment focusing ,laser - optical fiber coupling, optical fiber - fiber coupling, as well as light - sensor coupling. Coupling efficiency is usually greater than 90%. In order to achieve optical fiber and another fiber (or semiconductor laser) coupled , optical fiber end face placed in the focus of the ball lens, its output light into a parallel light, put another ball lens and optical fiber placed on its axis and make them focus and face overlap.
We are able to produce ball lens with ultra-high-precision diameter and surface quality,grade 10 . We can manufacture different materials and the range of 0.8-50mm diameter ball lens according customers requirements.
