Probe head of a coordinate measurement machine (CMM) measuring the dimensions of a silicon reference sphere. CMMs are used to make accurate 3D measurements of complex, precision-engineered components. Reference spheres are used to calibrate measuring machines such as CMMs. This CMM is manufactured by Zeiss.
