Ruby Ball Lens Details
We manufacture ruby balls in diameters ranging from 0.30mm to 5.0mm.
Ruby 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.
Ruby 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.
Applications which need wear resistance to metals and chemicals use ruby balls for longer life.
In terms of visual appearance, Ruby Ball can have a surface finish of No Scratch/Dig at 20x Magnification level (depending on the diameter of the Ruby ball lens).
Our Ruby raw material is produced by one of the oldest and most reliable supplier in the Swiss Industry.
Each and every Ruby ball is checked 100% for Size, Accuracy, Polish level and Cleaning before delivery.
All Ruby Ball products are cleaned and packed in Class 100 clean room area.
