Measurement and calibration capabilities
Picture 1 shows the calibration chain in the case of roughness measurement.
Traceable measurement techniques for surface characteristics are the basis for a concomitant quality assurance in research, development and production. In addition, a strong linkage of dimensional properties with other physical and chemical properties is characteristic, in particular, for micro-system technology and nanotechnology.
The "Surface Metrology" Department regards it as its goal to develop and improve measuring instruments and procedures for measurements on surfaces of micro-system technology, nanotechnology and general metrology (roughness, hardness and layer thickness metrology, etc.) in order to safely achieve smaller measurement uncertainties. For the dissemination of dimensional quantities to DAkks and industry, this also comprises the development and calibration of standards.
The Department participates in the redefinition of the Avogadro constant and is involved in a series of national and international research projects.
The measurement and calibration capabilities of the department 5.1 are available as pdf-file. They are integrated in the quality management system of the PTB, which meets the requirements for calibration and testing laboratories as defined in the DIN EN ISO/IEC 17025.T
