E5AT
A five-axis eucentric stage — unlimited rotation and ±90° tilt while keeping the region of interest centred, for ECCI, EBSD and tomography.

Ten by ten, then tilted#
The E5AT (Eucentric 5-Axis Table) is a 72 × 50 × 44 mm stage built so the area of interest never leaves the eucentric point, however far it is tilted or rotated. A four-axis substage — 10 mm of travel in both X and Y, 3 mm in Z, plus unlimited rotation — sits on a tilting platform whose positional encoder resolves ±90° of tilt to 0.1°, holding absolute accuracy under 0.4° (7 mrad). Linear-axis resolution runs below 0.02 nm; the rotation axis is available with its own encoder for applications that need R held to the same 0.4° accuracy.
From ECCI to a mounted gripper#
Because the region of interest tracks the tilt and rotation axes rather than sliding off them, the E5AT suits electron channelling contrast imaging, electron backscatter diffraction and tomography — any workflow built around repositioning a sample without losing eucentricity. An integrated microgripper can be fitted as an option, turning the stage into a manipulation platform at the same eucentric point rather than a separate tool swapped in afterwards.
