Ball lens

Ball lens are highly transparent spheres made of optical glasses. They are used as fiber interconnects in telecom and expanded beam connectors. Large ball lenses have been successfully used as collectors in LED lighting systems and medical devices. They have high coupling efficiency and should be much easier to align than traditional lenses due to its physical shape.

China Star Optics offers high quality custom designed optical ball lens in any quantity from testing sample to mass production. Extremely small MOQ helps to reduce your initial project investment.

- Capacities from 10 mm to 350 mm
- A variety of UV, VIS, IR materials and crystals available
- In accordance with RoHS Standard
- Custom upon your unique optical requirements

Ball lenses are great optical components for improving signal coupling between fibers, emitters, and detectors. They are also used in endoscopy, bar code scanning, ball pre-forms for aspheric lenses, and sensor applications. Ball lenses are manufactured from a single substrate of glass and can focus or collimate light, depending upon the geometry of the input source.

China Star Optics can provide different kinds of spherical lenses like Plano concave lens, Plano convex lens, achromatic lens. If you want to know more information about a plano-convex lens/mirror, such as the use and refractive index of a plano-convex lens, please contact us.
