Presentation of the microscope

The JEOL 2010F microscope, installed in CLYM, is a field-emission transmission electron microscope, with a resolution of 0.195 nm and a minimum probe size of 0.3 nm (0.5 nm, standard conditions). This TEM operates at 200kV and uses a Schottky field emitter. These characteristics make it a high-resolution and high-performance instrument for the characterization of a wide range of samples. A STEM device allows the acquisition of images in High Angle Annular Dark Field (HAADF).


Microscope features

The JEOL 2010F microscope is equipped with several analytical systems:

  • A DigiPEELS system (GATAN) with an optimal energy resolution of 0.65 eV (1-1.2 eV, standard conditions).

JEOL single-tilt and double-tilt sample holders are available as well as a tip for single-tilt tomography (+/- 85°).
