The SIOS Meßtechnik GmbH manufactures laserinterferometric and other types of precision instrumentation for measuring lengths, angles, vibratory motions and derived quantities like weights, forces, and pressures. The systems' work is mostly based on using of miniaturized laserinterferometers. These fiber-coupled lengths measurement devices with the remarkable resolution of 0,1 nm work very stable and precisely because of using a frequency-stabilized He-Ne laser as light source combined with environment's influence compensation for air pressure and temperature being relevant for lasers' wavelength. The distances of measurement amount to 5 m. Because of light-supplying to the sensor head via optic fibers the probe's environment is not influenced by temperature. The miniatur interferometers equipped with either cube corner retroreflector or plane mirror are used in two-axis and multiaxis systems, too. Furthermore velocity and vibration measurement is offered. Beside of fittable measurement devices, complete measuring equipment is developed and manufactured - according to the customers' requiries and measuring conditions.

SIOS Meßtechnik GmbH works as partner in the EU projects "PRONANO" and "Nano CMM".
