Transmission Electron Microscopy (TEM)

FEI Titan³ G2 60-300

The ASTEM (Austrian Scanning Transmission Electron Microscope) is a probe-corrected high end TEM/STEM system that is equipped for high resolution analytical research with unprecedented speed: thanks to the unique combination of a high-sensitivity SDD X-ray spectrometer (Super-X) and a high-resolution post-column energy filter (GIF Quantum) within one acquisition system, the microscope offers high speed (up to 1000 spectra/s) simultaneous EELS/EDS spectrum imaging for a wide range of analytical investigations for both light and heavy elements.

FEI Tecnai F20

This microscope is equipped with a monochromated FEG in combination with a Quantum energy filter and is the high end instrument of the institute at the moment. Besides classical methods (bright field and dark field imaging, selected area and convergent beam diffraction) various analytical methods (EDXS, EFTEM and EELS) as well as tomography are applied at both high spatial and high energy resolution. Furthermore, the microscope can be used in scanning transmission mode (STEM) supported by a novel digiscan unit allowing for high-speed spectrum imaging.

FEI Tecnai 12

In combination with the Bioscan camera, the T12 is a microscope aimed at biological research. However, it is used for a wide range of tasks such as investigations of not only biological samples but also polymers, thin films, fibers, ceramics, powders, single crystals and can also be used for acquisition of 3D tomography tilt series and microanalysis using EDXS.
