aspherical surfaces may be a major problem, for example in high-performance systems. At the
production of aspherical surfaces on the Optotech MCG100, vibration measurements were
performed in various operating modes. The measurement was done with VibXpert II. This
device uses piezoelectric sensors to record vibration acceleration. The measurement data were
then processed in Matlab software. The aim was to identify frequencies, which may have a
negative influence on optical element manufacturing, and also to outline possible causes of
their origin. In the observed spectrum (30-800 Hz), significant frequencies from several basic sources
were found. This is the tool spindle rotation, tool rotation, the axes control loop, and the
movement of the axes themselves.Workplace Institute of Plasma Physics Contact Vladimíra Kebza, kebza@ipp.cas.cz, Tel.: 266 052 975 Year of Publishing 2020 Electronic address http://acc-ern.tul.cz/archiv/PDF/ACC_2018_1_01.pdf
