Half Ball Lens
Half Ball Lens offer high transmission and low thermal expansion across the 200 nm to 2.2 �¼m wavelength range, making them ideal for demanding applications in the UV, visible, and near-infrared spectra. Ball lenses are commonly used to improve signal coupling between optical fibers, emitters, and detectors, as well as serving as objective lenses in endoscopy and barcode scanning systems. Hemispherical lenses simplify alignment and integration in optical setups.



Hongshen's fused silica ball and hemispherical lenses are uncoated and made from high-purity fused silica substrates. Available diameters range from 0.50 mm to 5.00 mm.

PARAMETER:
ODM Half Ball Lens are completely spherical lenses most commonly used to couple light in and out of fibres. Half-ball lenses are hemispheres.
BRD Optical supplies bespoke ball and half-ball lenses to our customers specifications. Ball lenses can be manufactured in quartz to have excellent UV and IR transmission between 185nm to 2000+nm, while sapphire lenses have a higher refractive index allowing a very short fall back length to better facilitate fibre coupling. Custom ball lenses are available in a range of alternative materials such as optical grade glass or even ceramics or IR crystal. Our half ball lenses offer uniform dispersion of light and typically used in LED displays and LED traffic lights.

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.)

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.

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.
