The ZEISS Diamond!Scan® carbo consists of a diamond-coated (ceramic) sphere that is glued onto a carbon fiber shaft. It is particularly suitable for scanning magnetic materials where styli with a hard metal shaft cannot be used. They are primarily used for the measurement of permanent-magnetic stator parts in electric engines. Coated spheres have a higher roundness as solid diamond spheres. ZEISS Diamond!Scan® carbo is available in diameters of 1, 2, 3, 5 and 8 mm.
