Ball Lenses are widely used for focusing & coupling light into & out of fibres. With the high refractive index of Sapphire (Al2O3) material, it yields a low spherical aberration that can be used in the range of UV from 200nm up to 5µm, and with it being one of the hardest materials they are resistant to damage. The key feature of ball lenses is their short back focal length allowing for precision coupling where size or space is a limiting factor in the system. Typically used in pairs, where one lens acts as collimator for the second to focus the light back into the coupled fibre. Ball Lenses are manufactured from a single substrate of glad and therefore, depending on the geometry of the input source, can focus or collimate light. Half Ball Lenses can also be used as an interchange with a full ball lens for more compact designs. Read the PDF for more information...
