Production sequence of Si-spheres and interferometrical determination of the sphere volume



To ensure that the components or entire units of test equipment to the high accuracy requirements for production and material properties are, continuously during and after production checks instead. The necessary instruments are found in the direct manufacturing environment and in a temperature-controlled environment. Particularly for the manufacture of precision components can also direct the development of suitable measurement technique performed in the machining center.

No longer suffice unless the already very good opportunities for production measurement technology in their own department, may be made to the respective areas of expertise within the entire metrology PTB.
