Visiting PTB


Would you like to know how our atomic clocks tick? When even a nanometer is too long? Or all the things that physicists do with light? If you are interested in these or similar questions, then PTB, the National Metrology Institute of Germany, is the right place for you. Groups of at least 7 and up to a maximum of 30 people can register for our visitors' service. This usually consists of an introductory talk followed by a tour of several of our laboratories. (The labs are spread over our campus which is approx. 1 km2 in size, so you ought to be a good walker.)

Aufgrund der Vorgaben und Empfehlungen der Bundesregierung zur Eindämmung der Corona-Pandemie können derzeit keine Besuchergruppen in der PTB empfangen werden. Sobald Sie wieder hinter PTB-Kulissen schauen können, werden wir Sie an dieser Stelle darüber informieren.
