Half-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.Fused silica balls are ideal for the most demanding ball lens applications in the ultraviolet, visible, and near infrared spectra. Sapphire balls has superior optical transmission qualities. Ruby Balls are easier to see and therefore easier to handle for physical applications.

Half ball(hemispherical)lenses are ideal for applications such as fiber communication,endoscopy,microscopy,optical pick-up devices and laser interferometry and measurement.
