Increasing demands on the accuracies of coordinate measuring machines, machine tools and positioning devices with movement ranges over several metres pose a challenge to measurement systems when it comes to their acceptance and calibration. In this context, new generation laser interferometers offer unique properties that combine a large length measuring range with an extraordinarily high resolution. read more
