Ball lenses are commonly used for laser collimating and focusing, laser-to-fiber coupling, fiber-to-fiber coupling, Solar-photovoltaic and fiber-to-detector coupling. Worldhawk can provide spherical ball lenses and half ball lenses in a range of substrates for performance in the ultraviolet to the NIR. Such as including H-K9L(N-BK7), Sapphire, CaF2, BaF2, ZnSe or custom materials upon request. Ball lenses feature short back focal lengths to minimize the distance needed from the ball Lens to the optical fiber. Ball lenses are commonly used to improve signal quality in fiber coupling applications, or for use in endoscopy or bar code scanning applications. Half-Ball (hemispherical) lenses are ideal for applications such as fiber communication,endoscopy, microscopy, optical pick-up devices,and laser measurement systems.
Optical sapphire ball lens and half ball lens are both made from Al203, it's ideal for demanding applications (such as laser systems). They have a lot of advantages: 1/ Stronger than standard optical glass,they have extreme surface hardness, high thermal conductivity, high dielectric constant and resistance to common chemical acids and alkalis. 2/ Transmits Wavelengths Ranging From UV to Mid-Infrared (0.2 - 5.5µm.) Materials characteristic Refractive index (nd) 1.768 Coefficient of dispersion (Vd) 72.2 Density (g/cm3) 3.97 TCE (μm/m) 5.3 Soften Temperature () 2000 Knoop hardness (kg/mm2) 2200 About sapphire materials for our ball lenses We only choose the best sapphire material to process the ball lens and hemispherical half ball lenses for our customers. As you know, sapphire has higher performance and higher purity near the center in the process of growing. So only the ball lens made from this part of the material has better performance.
