The history of SIOS Meßtechnik GmbH begins in November 1991 with its spin-off from the Institute for Process Measurement and Sensor Technology at the Technical University of Ilmenau.
The founders of the company are Prof. Dr. Gerd Jäger, Dr. Walter Schott – at the same time the first and longtime managing director – Prof. Dr. Rainer Grünwald, Dr. Hans-Joachim Büchner and Dr. Detlef Heydenbluth, who contributed their extensive know-how as the basis for the company’s activities. The founders started with the goal of developing the potential of laser interferometry at the highest level of measurement technology for practical applications and thus making the world of measurement technology even more accurate and precise.
In the meantime, SIOS is not only one of the leading manufacturers of laser interferometric measurement systems, but also one of the most important European suppliers of stabilized He-Ne lasers as metrological light sources with highly stable wavelengths. In addition, SIOS is a supplier of the world’s most accurate positioning system with its NMM nanopositioning and nanometrology machine, making it the sole market leader.
