Orientation and Phase Mapping in TEM (EBSD-TEM) - ASTAR

ASTAR can turn any TEM into a very powerful analytical tool enabling orientation phase imaging at 1 nm resolution attainable (FEG TEM) in combination with other TEM Bibliography analytical techniques. The Precession Electron Device Spinning Star will change your conventional TEM into a powerful crystallography study tool. Any diffraction pattern recorded in precession conditions shows quantitative data of the diffraction pattern, practically free of dynamical effects. This unique feature allows to observe the true symmetries of the (nano) crystal being observed. It permits also to record the true intensities on each diffraction spot, giving access to calculation of the crystal structure. This feature makes now readily available structure determination on nanocrystals, using your conventional TEM.

TEM Orientation Imaging - ASTAR Specification
