Ball Lenses are glass spheres commonly used in fiber optic applications. ideal for focusing light into fibers, as well as fiber coupling. The ratio of the collimated light input beam diameter to the ball lens diameter is defined as d/D. as the ratio increases, the back focal length increases.
For this spherical ball lenses we can make them from all of the glass material
