Features

Ball Lenses are commonly used to improve signal quality in fiber coupling applications, or for use in endoscopy or bar code scanning applications. Ball Lenses feature short back focal lengths to minimize the distance needed from the Ball Lens to the optical fiber. Uni Optics offers a variety of Ball Lenses in a range of substrates for performance in the ultraviolet to the NIR.

Ball lens are highly transparent spheres made of optical glasses.They are used as fiber interconnects in telecom and expanded beam connectors.Large ball lenses have been successfully used as collectors in LED lighting systems and medical devices.They have high coupling efficiency and should be much easier to align than traditional lenses due to its physical shape.
