Sapphire Ball

Best quality Sapphire ball lens

Sapphire Ball Lens Details

Industrial technologies manufacture saphire / sapphire balls in diameters ranging from 0.30mm to 5.0mm.

Sapphire is one of hardest known material with consistent quality available on a commercially economical scale.

With a hardness of 2300 HV it is much more harder then most of the known hard materials like ceramics, etc.

Saphire raw material is grown in a factory by Melting ultra pure Al2O3 at temperature higher then 2000 deg. Celcius to create a single crystal. This hard material has the ability to be polished to a very good surface finish.

The refractive index of sapphire is 1.760 which makes it very interesting to be used as a sapphire Ball lens for optical telecom products. In addition to the optical properties of Sapphire, it is also wear resistant and can withstand severe chemical corrosion.

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

Our Sapphire raw material is produced by one of the oldest and most reliable supplier in the Swiss Industry.

Each and every Saphire ball is checked 100% for Size, Accuracy, Polish level and Cleaning before delivery.

All Sapphire Ball products are cleaned and packed in Class 100 clean room area.
