Research

The research conducted in the unit is of highest international quality, in many of these areas, and the cooperation tight with several ICT and other high-tech companies.

With these companies, we boost practical applications that create societal impact.

Metrology Research Institute

Metrology Research Institute focuses on optical radiation measurements and related activities. We do not forecast the weather!
