Ball lenses are commonly used to improve signal quality and coupling efficiencey between an optical fiber emitter and optical fiber detector, which is used in endoscopy, bar code scanning, pre-processing material of Aspheric Lens etc. The short back focal length can be used to reduce the necessary distance from the ball lens to the optical fiber.
