FEI Magellan 400
The FEI Magellan 400, an extreme high-resolution SEM with sub-nanometer resolution, operates at 1 to 30keV. An in-situ plasma cleaner and a liquid nitrogen cold finger allow for the analysis of highly labile and sensitive materials. SEM analysis of non-conductive materials, carried out at low beam energies, enables characterization of sub-nanometer surface structures. Novel detectors such as the high collection efficiency in-lens detector and a unique low voltage, high contrast solid state detector, combined with a two-mode objective lens with beam deceleration and immersion capabilities, provide high surface sensitivity, high resolution and enhanced contrast at low voltages.
The JEOL JSM-7000F equipped with a Schottky field emission gun offers high resolution and large probe currents at small probe diameters permitting characterization of nano-scale structures. A multipurpose specimen chamber, motorized specimen stage, single-action specimen exchange and an ideal geometry for techniques such as energy dispersive spectroscopy, electron backscattered diffraction and e-beam lithography are also features of this instrument. Resolutions of 1.2nm at 30keV and 3.0nm at 1keV make it an ideal instrument for the study of nano-scale non-conductive materials, polymers, ceramics and semi-conductors. An integrated Oxford Synergy system with INCA EDS X-ray micro-analysis, HKL EBSD and CHANNEL 5 software package allows for the simultaneous acquisition of chemical and crystallographic data, permitting a complete characterization of poly-phase samples.
The JEOL 6610LV is a tungsten filament equipped SEM with selectable low vacuum mode that allows for the analysis of non-conductive specimens without the need for heavy-metal coating. It has a large chamber which enables observation of specimens up to 200mm in diameter. With a resolution of 3.0nm at 30keV it is possible to view secondary electron and backscattered composition images simultaneously, which allows the user to contrast and compare specific details of the sample while carrying out EDS analysis and 3D measurements from stereo images.
