Identification of mid-spatial frequency error on the optotech MCG 100 when grinding optical elements

Popis výsledku v původním jazyce

The mid-spatial frequency errors, surface defects arising from the production of optical naspherical surfaces may be a major problem, for example in high-performance systems. At the nproduction of aspherical surfaces on the Optotech MCG100, vibration measurements were nperformed in various operating modes. The measurement was done with VibXpert II. This ndevice uses piezoelectric sensors to record vibration acceleration. The measurement data were nthen processed in Matlab software. The aim was to identify frequencies, which may have a nnegative influence on optical element manufacturing, and also to outline possible causes of ntheir origin. In the observed spectrum (30-800 Hz), significant frequencies from several basic sources nwere found. This is the tool spindle rotation, tool rotation, the axes control loop, and the nmovement of the axes themselves.
