Our Highlights

The ultra-stable SP-DI laser interferometers can be used both for long-term measurements in research and development, e.g. for material analyses, and in compact design (SP-DI/F) as feedback sensors for positioning systems in industrial environments. They are characterized by a unique thermal stability of less than 10 nm/K.


Kalibrier-Laserinterferometer SP 15000 C5The SP 15000 C5 calibration laser interferometer was developed to meet the requirements of machine and equipment manufacturers. Length, angle and straightness can be measured simultaneously with high accuracy. Due to the compact straightness option, the setup and adjustment of the measuring systems is very easy and quick, even in confined spaces. Straightness can be measured over a length of 6.5 meters.

1st WORLD Interferometry DAY

We call together with the TU Ilmenau tothe 1st WORLD Interferometry DAY on April 14, 2021. We would like to inspire as many people as possible around the world to participate in our day of action. The initiators Dr.-Ing. Denis Dontsov (Managing Director SIOS Meßtechnik GmbH) and Univ.-Prof. Dr.-Ing. habil.…

SIOS starts up again!

Our staff “survived” the holidays safely in the smallest circles of family, taking into account the current lockdown measures in Germany. The general tone is that it was quiet, a bit more boring, adult children, friends and relatives were missed. Thanks to modern technology, we could at least “meet” each…
