Nanometrology at VTT MIKES

 

Services and competences in nanometrology

VTT MIKES has extensive expertise in nanoscale measurements. The main advantage of these measurements at VTT MIKES is the traceability and reliability of the measurement results. Moreover, we always provide realistic uncertainty estimates for the measurements and our calibration services are internationally accepted.

Solving customer problems often requires more versatile know-how than only performing single measurements. Problem solving contains for instance answering the following questions: What is the problem? What method would it take to solve it? What level of precision is required? At VTT MIKES, we have a wide range of different measurement methods available in the nanometre and micrometre range to solve the customer problems.

The size of customer projects varies from individual measurement services to customer-funded research projects and large co-financed research projects. For larger research projects, we can help with applying for funding (e.g. Business Finland) or we can put together a bigger consortium to solve the problem (EU H2020).
