High Angle Annular Dark Field (HAADF) Scanning Transmission Electron Microscopy (STEM) is a very powerful technique to provide direct information on a local chemistry of nano-materials at atomic scale. Using the retrofit Deben Annular STEM, SEM users can acquire HAADF transmitted electron images for a fraction of the cost of a dedicated Transmission Electron Microscope (TEM) with HAADF detector fitted.
Twelve 3mm grids can be fitted to the STEM grid holder, allowing multiple specimen analysis. A retractable arm complete with Deben Gen5 electronics allows the STEM Detector to be used with any SEM with a suitable free chamber port and AUX video input. The 12 position grid holder is airlock compatible and is supplied complete with a stage dovetail/sledge as required.
