Ball lenses are, as the name suggests, completely spherical lenses most commonly used to couple light in and out of fibres. Knight Optical supplies a range of stock ball lenses as well as bespoke designs to your own specifications. Our stock ball lenses offered in quartz have excellent UV and IR transmission between 185nm to 2000+nm, while our sapphire lens have a higher refractive index, allowing a very short fall back length to better facilitate fibre coupling. We can supply ball lens in a range of alternative materials and diameters. We are able to supply high precision grade 3 ball lenses, mid-range grade 25 ball lenses and commercial grade 100 ball lenses offering all grades to suit any application.
Aside from fibre coupling applications, ball lenses are also used as objective lenses in endoscopy, laser measurement systems and bar-code scanning.
Our half ball lenses offer uniform dispersion of light and typically used in LED displays and LED traffic lights.
