Half-ball (hemispherical) lens are ideal for applications such as fiber communication, endoscopy, microscopy, optical pick-up devices, and laser measurement systems.
We also supply a range of half-ball lenses, which are available in optical glass, and sapphire. These half-ball lenses can have Anti-Reflective (AR) Coating. Half ball lenses give uniform light dispersion which makes them very good for LED traffic lights and LED display systems.
