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.
Sapphire has superior optical transmission qualities for ball lens and half ball lens.

Spherical Lens Half Ball Lens
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.
Sjllaser Technology Limited manufacture micro ball lens ranges in diameter from 0.3mm to 3mm.

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.
Fused quartz from 200nm to 2.2um has high transmittance and low thermal expansion coefficient, which makes it an ideal choice for spherical lens in ultraviolet ray, visible light and near infrared spectrum applications with strict requirements. Spherical lens is commonly used to improve signal coupling between optical fibers, transmitters and detectors, as well as objective lenses in endoscopy and bar code scanning applications.
Hemispherical lens simplify the integration of the whole system.

Disinfection UVC LED Strips
Why Does it Have to be UV-C?
The reason why the correct UV wavelength for sterilization applications is absolutely critical is the mechanism of pathogen inactivation. DNA and RNA are the foundation of life, including microscopic organisms and pathogens such as viruses, bacteria and molds. Without this genetic material, the pathogen will not be able to multiply and eventually cause the death of the infected colony.
