DESCRIPTION

The Cryo Translation Stage (CTS) is a positioning device driven by a JPE’s Cryo Linear Actuator (CLA). It combines a large traveling range with high positioning resolution and high stability. Identical single axis stages can simply be stacked into a xy configuration or even xyz using optional brackets.

* This is not play but predictable and highly repeatable. The motion will be pure translational, perpendicular to the sample table plane, without rotations. Its origin lies in simple kinematics from the parallel leafspring flexure guide. In multiple axis systems this will occur for each axis, but than also can be compensated.
** The CLA (not the sample table) can be moved past the negative endstop. The CLA will loose its minimal required preload and might not move anymore. Manual action could be required to restore this.
