ASTAR device uses novel TEM based orientation mapping technique to characterize any material up to 1 nm scale based on collection of precession electron diffraction patterns (PED).

In combination with TOPSPIN simultaneous  orientation /phase /strain /STEM maps are possible.

Novel Automated Strain Mapping Solution for TEM/STEM (Patent pending) based  on nanobeam precession  diffraction patterns and STEM reference image acquisition. Precision up to 0.02% (200kV FEG) with spatial resolution  < 2 nm (FEG  TEM). In combination with TOPSPIN simultaneous  orientation /phase /strain /STEM maps are possible.

3D diffraction tomography in combination with DigiSTAR precession  diffraction device enable automatic reconstruction of reciprocal cell of any material  and solve any nanocrystalline  structure.

Beam Precession with DigiSTAR may enhance EELS & EDX signal reducing channeling effects. EELS quantification  possible via TOPSPIN model based EELS quantification.

TOPSPIN is a digital STEM, beam Precession Electron Diffraction  analytical Experimental framework offering a suite of beam precession imaging and advanced analytical experiments.

Researchers at Cambridge  University  and NanoMEGAS 

reveal detailed  organic thin film structure  with  ASTAR  

TEM orientation mapping, is becoming an increasingly popular and important technique. There has been significant instrumental development in recent years by the SME involved in JRA1, Nanomegas, enabling precession electron diffraction (PED) patterns to be acquired pixel by pixel across a scanned area. Such 4D data sets can be analysed to provide high  resolution (ca. 1nm) phase-identification and orientation maps.
