Small Size, High Resolution and Accuracy
S21 adopts principle of mechanism amplification design, which can achieve maximum rotation of 7.5mrad. It is very compact, and its size is only 60×60×15mm. It is very easy to integrate into precision rotating equipment. |
Driving and Control
S21 rotation stage needs a piezo controller with 1-channel voltage output. The S21 closed-loop version can be equipped with E01 series closed-loop controller to realize θz high-precision rotary positioning control. |
Application Case-Precision Positionin S21 piezo rotation stage can be used with CoreTomorrow's any linear or tilting stage to form a multi-axis precision positioning operations.
