Glass Ball Lens Details

Industrial technologies made glass ball lenses from a wide variety of optical glasses with refractive index ranging from 1.50 to 2.10.

We Manufacture Glass ball lenses range in diameter from 0.40mm to 8.0mm.

They can achieve a very high level of surface finish depending on the application of the product. Our Glass Ball lenses can achieve a surface finish of Ra = 1.2nm.

In terms of visual appearance, Our Glass Ball Lens can have a surface finish of No Scratch/Dig at 20x Magnification level (depending on the diameter of the Glass ball lens).

The optical glasses used for making these Glass ball lens are purchased from various renowned optical glass material makers like Ohara, Sumita, Schott, etc. which have a strict control on the nd and vd value of the glasses.

Glass ball lenses are used to improve signal coupling between Emitters, Fibres, Transmitters, Receivers and Detectors depending on the application.
