The Federal Institute of Metrology METAS is the Swiss National Metrology Institute. It was founded more than 150 years ago and has over 200 employees. Its tasks cover R&D activities on basic and applied metrology, work on legal metrology and much importance is attributed to the provision of commercial calibration and measurement services for industry and research (

The Laboratory for Length, Nano- and Microtechnology has extensive knowledge in the field of dimensional metrology. It has built a highly accurate micro-coordinate measuring machine (micro-CMM), which contributes to international comparisons, research projects, and calibration services. Furthermore, it recently developed a metrology X-ray computed tomography (CT) system. The particularly stable and comprehensively characterized setup enables measuring small workpieces containing micrometer sized features.

METAS leads work package 1 addressing the development of CT geometry measurement procedures, manufacturing and calibration of reference objects, and transfer of the gained knowledge into industry and to measurement service providers.
