Stainless steel ball – for tactile systems
 

Ball made of stainless steel for measurements with tactile systems. Stainless steel ist corrosion-resistant. The ball’s midpoint is determined by a ball measurement

Roundness of 1.5" (38.1 mm) balls	0.2µm- 0.5µm

Matte stainless steel ball – for laser scanners
 

Matte stainless steel balls are used for check and calibration of white light or laser scanning systems.

Feasible sizes	1.5" (38.1mm), 0.5" (12.7 mm) and 50 mm other sizes upon request
Roundness of 1.5" (38.1mm) balls	<3 µm

Ceramic ball – for scanners and tactile systems
 

Ball made of ceramic for measurements with optical area scanning systems on the basis of white light fringe projection or laser scanners, as well as for tactile systems. In comparison to balls made of aluminium oxide ceramic (Al2O3), our special ceramic has the advantage that it can be measured directly under different lighting conditions without further pre- and/or after-treatment. Its surface is of a diffusely scattering nature and fulfils all requirements of the VDI/VDE guideline 2634.
 

The balls are made of our special ceramic. This ceramic has been optimized for the specific properties of a scanner based on white light fringe projection. Furthermore, in numerous benchmarks carried out by equipment manufacturers and customers, it demonstrated its superiority to other balls made of ceramic (e.g. aluminium oxide) as well as to coated balls made of steel. Next to good “optical” properties of our special ceramic, our balls feature a high precision roundness (<2 μm).
