Fused Silica Ball and Half-Ball Lenses

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.



1. What’s the Ball lenses?

 

Ball lenses are highly transparent spheres made of optical glasses. They are used to focus light into fibers as in diode laser-to-fiber coupling as well as fiber-to-fiber coupling. They have high coupling efficiency and should be much easier to align than traditional lenses due to their physical shape. Uni Optics offers a variety of Ball Lenses in a range of substrates for performance in the ultraviolet to the NIR.


2. What are the ball lenses used for?


Ball Lenses are commonly used to improve signal quality in fiber coupling applications, or for use in endoscopy, bar code scanning and sensor applications. Ball Lenses feature short back focal lengths to minimize the distance needed from the Ball Lens to the optical fiber.
