  • STEM Imaging in both Bright field and Annular Dark Field modes
  • Energy Dispersive X-Ray Spectoscopy for Microanalysis and mapping​
  • Electron Diffraction​
  • Tomography​
  • 3D precession electron diffraction tomography- The limitations of X-Ray diffraction  with nanostructures of nm size level can be solved by the application of the precession electron diffraction  technique by increasing the kinematical character of the electron diffraction.​

TIA is now available offline, please see a member of MAI Staff for access.

Images and data saved in TIA’s propriety format (.emi) can be open without the TIA software using an ImageJ plugin.
