Glass Ball lenses with Refractive Index higher then 1.80 is classified under this category of High Index Glass Ball.
With higher coupling efficiency required for Transmitters and Receivers, the application of this High Index Glass Ball lens is becoming more and more popular.
The use of High Index Glass Ball results in reduction of Back Focal Length, as a result the shorter distance simplifies fibre coupling.
We manufacture High Index Glass Ball lens in diameters ranging from 0.40mm until 8.0mm
They can achieve a very high level of surface finish depending on the application of the product. Our High Index Glass ball lenses can achieve a surface finish of Ra = 1.2nm
In terms of visual appearance, our High Index Glass Ball can have a surface finish of No Scratch/Dig at 20x Magnification level (depending on the diameter of theHigh Index Glass Ball).
All our High Index Glass Balls are cleaned and packed in Class 100 clean room area.
Some of the most common high index glasses are as follows:
