Constant-strut-length hexapod
The constant-strut-length hexapod mechanism is well suited for mirror manipulation in UHV, especially for combined beam switching and beam splitting or for mirror exchange. The parallel-kinematic approach allows for free definition of the rotation center for pitch, roll and yaw, higher stability, repeatability and load capacity as compared to a stacked design. Mirror exchange units can be realized using a very compact design. The large rotational range travelled in a few seconds enables polarization switching e. g. for XMCD experiments.
