Measurements of Three-Dimensional Freeform and Aspheric Geometries
The ›NMM-1‹ nanomeasuring machine, developed at the Technical University of Ilmenau, Institute for Process Measurement and Sensor Technology and produced by SIOS Messtechnik GmbH, provides the opportunity for conducting many different types of measurements in nanometer range . The NMM-1’s excellent metrological characteristics are being exploited for calibrating transfer standards, such as step-height standards, one-dimensional and two-dimensional lateral-displacement standards, flatness standards and roughness standards, at several government institutions around the world. The NNM-1 exhibits 0.1nm resolution in a measurement volume of 25x25x5mm3 and can be equipped with various types of probe systems , .
