You find a survey of the areas of PTB activities in the illustrated brochures the PTB offers on numerous subjects. The following brochures have so far been published.
A short summary of PTB
PTB The National Metrology Institute (5.34 Mb) PTB Info Sheet: PTB the National Metrology Institute of Germany
Info Sheet Division 1 Mechanics and Acoustics (640.58 kb) How heavy, how strong, how fast, how loud? Division 1 is your reference for the precision measurement of mechanic and acoustic quantities. In addition to basic research, the main task of this Division is to supply services, i. e. calibrations in the field of industrial metrology and type tests in the field of legal metrology.
Info Sheet Division 2 Electricity (788.72 kb) Electric measurements are of a multidisciplinary nature. In almost all industrial, technical and scientific fields, in medicine as well as in environmental and climate observation, non-electric measurands are transformed into electric quantities. This is the reason why electric measurements play a key role in metrology.
Info Sheet Division 4 Optics (672.23 kb) What time is it? How long is one metre? How is luminous intensity measured? But also: What is the colour, power or spatial distribution of a light-emitting diode? How strong is a laser, or how smooth is a mirror? How is optical quality measured and how are atoms counted? These and many other questions are dealt with by the Optics Division, because they can be answered very precisely with the aid of modern optical methods.
Info Sheet Division 5 Precision Engineering (614.96 kb) In many important technical branches of industry, length measuring techniques provide the basis for a stable and sustainable production. Here, the traceability of such measurements to the unit ?metre? is a precondition for globally distributed manufacturing, because it guarantees that everywhere on earth, the same measure is valid. Quality systems are based on this proof of an uninterrupted metrological chain which reaches up to the national standards at its top of the hierarchy.
Info Sheet Division 8 Medical Physics and Metrological Information Technology (741.31 kb) Medical physics and Metrological Information technology
Developing measuring methods and measuring procedures in medicine is one major task of Division 8. Furthermore, the other is information technology ? from mathematical modelling and software testing to the approval of gaming and voting machines.
Info Sheet Clean Room Center (702.71 kb) The Clean Room Center of PTB is used to fabricate micro- and nanoelectronic circuits for electrical quantum metrology, to advance microand nanometrology, to perform ultra-precise angle and coordinate measurements, and to push the limits of optical metrology.
Info Sheet: The PTB (805.73 kb) Accurately? Yes, accurately! But higher accuracy is always possible. The Physikalisch-Technische Bundesanstalt (PTB) tries to achieve this. PTB is the National Metrology Institute of Germany with scientific and technical service tasks. It measures with the highest accuracy and reliability ? metrology as the core competence.
