Alkor Technologies - manufacturer of ball lenses. We can make small ball lenses from diameter 2mm and large lenses up to diameter 90mm.
Spherical ball lenses are commonly used for laser collimating and focusing, laser-to-fiber coupling, fiber-to-fiber coupling, and fiber-to-detector coupling. Ball lenses have very low spherical aberration and so focus and collimate light very accurately. They are available economically at very high precision and are simple to mount. Sapphire ball can be used from 200nm to 5.3μm and has exceptional hardness, strength and temperature resistance. N-BK7, Sapphire and Fused Silica ball lenses avaialable upon request.
