1. DigiSTAR  digital precession electron  diffraction  unit  is easily  retrofit to any TEM 100- 300 KV  (LaB6 /W - FEG) , alignments  are stored  in  memory.

  1. Ab-initio structure  determination of  (any nanostructure) metals, ceramics, polymers, semiconductors, pharmaceuticals   using  precession  electron

diffraction  intensities.

  1. Precession semi-angle  variable from 0- 85 mrad  (TEM dependent), spot distortion correction-compensation  at  high  angles ( > 15 mrad )

  1. Precession   frequency  variable  from   0.3-2.3  kHz (TEM dependent), suitable for  beam  sensitive   samples   

  1. Easy  symmetry  determination  for nanocrystals  (space and point group)

  1. Accurate  stoichiometry  refinement   for  nanostructures 

  1. DigiSTAR can be easily retrofitted  into  various TEM  in the same laboratory and can upgrade /enhance  TEM functionalities  for  electron  crystallography  :
