What sios does

SIOS Meßtechnik GmbH is a privately held German precision measurement technology company founded in 1992 and headquartered in Ilmenau, Thuringia. The firm develops and manufactures laser interferometric metrology systems for the measurement of length, angle, vibration, straightness, temperature, and force at sub-nanometer resolution. Its flagship product, the NMM-1 Nanopositioning and Nanomeasuring Machine, is positioned as the only metrological system capable of sub-nanometer accuracy measurements on macroscopic objects under normal conditions, employing three miniature interferometers whose beams intersect virtually at the measurement point to satisfy Abbé's comparator principle across all three axes. The product portfolio also includes the Nano Vibration Analyzer NA (5 pm amplitude resolution, 0-5 MHz range), length and angle measurement systems, calibration interferometers, stabilized He-Ne lasers, environmental metrology instruments, gauging probes, and metrology software (NMM Control, InfasVIBRO).

The business model is built on one-time hardware sales of high-precision instruments, supplemented by custom OEM solutions for specific customer requirements and calibration systems. SIOS sells direct from its Ilmenau headquarters and through a network of 23 international representatives covering 30 countries across Europe, North America, Asia, and Oceania. Customer segments span scientific research institutions, calibration and metrology laboratories (including national metrological institutes), precision machine builders, semiconductor manufacturers, medical technology firms, and microtechnology/MEMS companies. Pricing is quote-based and not publicly disclosed, with multi-year contracts and per-project OEM arrangements.

The firm operates as a founder/management-led GmbH under Managing Director Dr. Denis Dontsov, with Prof. Gerd Jäger as founder. It maintains active R&D partnerships with TU Ilmenau/IPMS and IMMS, and is co-financed by the Free State of Thuringia and the European Union through EFRE/ESF+ programs. The company was recognized as a Top 100 Innovator 2025 at the Deutscher Mittelstands-Summit. Revenue and headcount are not publicly disclosed.

Core offering

SIOS Meßtechnik GmbH develops and manufactures laser interferometric measurement systems and precision measuring instruments for calibration and nanometrology. Its portfolio spans length, angle, vibration, straightness, temperature, and force measurement instruments — including the flagship NMM-1 Nanopositioning and Nanomeasuring Machine, the Nano Vibration Analyzer NA, calibration interferometers, stabilized He-Ne lasers, gauging probes, and metrology software. The company also delivers custom-engineered OEM solutions built on its modular sensor architecture for integration into third-party products and production environments.

Product overview

SIOS Meßtechnik GmbH develops and manufactures laser interferometric precision measurement technology and instruments for calibration and nanometrology. The product portfolio includes the NMM-1 Nanopositioning and Nanomeasuring Machine as the flagship offering, the Nano Vibration Analyzer NA for microstructural vibration analysis, length and angle measurement systems, calibration interferometers, vibration measurement systems, gauging probes (including laser focus sensors, white light sensors, atomic force microscopes, and 3D microprobes), stabilized He-Ne lasers, environmental metrology instruments, metrology software (NMM Control, InfasVIBRO), and custom OEM solutions. These products work together as an integrated metrology ecosystem: stabilized lasers serve as the wavelength standard powering all interferometric sensors, which feed into length, angle, and calibration systems, with environmental sensors compensating atmospheric influences and software platforms providing data acquisition, FFT analysis, and user control across the full product range.
