From 21 to June 23, 2016 our third representative training took place in the 2-year-spacing with 13 representative offices from around the world. Among many presentations there was time for an extensive practical training. Above all, our new devices were introduced, at the first place our Calibration Interferometer SP 15000 C5 with its features and capabilities. Particularly impressive was the measurement at one of our CNC machines in the mechanical workshop. The AfM software was kindly presented by our colleagues from AfM. It was also taken care of the culinary and cultural framing. Now the 16 representatives can go professionally fit and well motivated to work.
