Optical Ball Beam with mat spheres
The new ISO 10360-8 on verification of optical measurement systems asks for more lengths to be measured than the VDI/VDE 2634. Thus here one sees our corresponding ball beam made with either "normal" spheres or mat steel spheres or low volume scattering ceramic spheres. For fringe projection the latter is indispensable.
Different diameters and lengths are possible.
Typical is a 15 mm diameter.
Lengths range from 100 mm to 3 m.
