        The compact rotary stages can be used in optical applications, where B. Position filters reliably and with excellent repeatability. Rotary tables can be flexibly integrated in multi-axis combinations and can be mounted on suitable linear tables without an adapter.
      • Miniature hexapods
        The most compact products for movement with 6 degrees of freedom are based on Q-Motion® piezo motor tables. But only hand-sized hexapods with brushless DC motors (BLDC) are available. Classic parallel kinematic hexapod design results in the most uniform possible performance in the axes. For long linear travel ranges, a design with a low overall height may be better.
