Jeol JEM2100F TEM
The Jeol 2100F electron microscope is a high resolution scanning/transmission electron microscope equipped with Schottky field emission gun (FEG). It is well suited for material sciences, and can be operated at voltages between 80-200 kV in both, the transmission (TEM) mode and the scanning transmission (STEM) mode.
Additionally, it offers chemical analysis and tomography capabilities. It is well suited for high-resolution imaging in the TEM mode, and atomic resolution can be achieved due to the high resolution objective lens polepiece. Z-contrast imaging is possible in the STEM mode using the bright field (BF) and high angle annular dark field (HAADF) STEM detectors. Specimen tilts of ±30° are possible with the regular sample holder, tilts up to approximately ±80° with a high tilt holder. An Oxford energy dispersive X-ray analysis system allows elemental analysis. The high tilt holder in combination with the Tomography software allows 3D-rendering of samples. Digitized image documentation is achieved via two retractable CCD cameras.
