Ball Lenses
Ball lenses are spherical optical components, typically made from glass or other transparent materials. These glass ball lens used primarily for focusing and collimating light in a wide range of applications, including fiber optic communications, endoscopy, microscopy, optical pick-up devices, and laser measurement systems. The simple geometry of the glass ball lens allows for minimal light deviation and aberration, making them highly effective in coupling light between fibers or focusing light into a small area. Their efficiency and compact size make fiber ball lens indispensable in precision optical instruments and devices requiring high-quality light transmission and focusing.

Types of Ball Lenses
Optical Ball Lenses
Ball lenses focus and collimate light, essential in fiber optics, microscopy, and laser alignment, offering minimal light deviation.

Half Ball Lenses
Half ball lenses offer precise focusing and collimation, ideal for enhancing optical performance in imaging and sensor applications.

How Do Ball Lenses Work?
Ball lenses function by refracting light as it passes through their spherical surface, focusing or collimating the light rays. Their geometry allows for minimal optical aberration, making them ideal for coupling light into and out of fibers. When light enters a ball lens, it bends towards the lensâ?? denser medium, converging at a point on the opposite side. The precise focal point depends on the lens materialâ??s refractive index and the diameter of the ball lens, enabling applications in fiber optics, laser collimation, and optical instrumentation.

This product is polished spherical lenses made by optical glass fused silica, sapphire or other optical materials which have relatively high transmission rate for a diode with an anti-reflection coating. Widely used for coupling light in and out of fibers. It has the advantage of easy for fabrication, light weight which can be considered as the ideal components for optical communication applications.

Although due to the spherical aberration which leads to lower coupling efficiency, its unique easy-packaging attribute guaranteed ball lenses are suitable for series production for optical communication applications with no doubts, especially compared to aspheric lenses.

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.
