QED acquires large-angle CBED and PED by controlling incident beam direction, while EDT acquires 3D electron diffraction by controlling incident beam deflectors as well as a goniometer. In addition, QED also allows automatic acquisition of ALCHEMI data.

• QED (Quantitative Electron Diffraction)
  The QED gives LARBED (Large Angle Rocking Beam Electron Diffraction) and/or PED (Precession Electron Diffraction) patterns by controlling the electron beam in your TEM without any additional hardware. In addition, ALCHEMI data can be acquired by controlling incident beam direction.
  
  
• EDT (Electron Diffraction Tomography)
  The EDT/Collect acquires 3D EDT by controlling the electron beam and the goniometer of your TEM.
