Dual Beam FIB/SEM

ZEISS AURIGA CROSSBEAM FIB/SEM

The Zeiss Dual Beam FIB/SEM instrument is located in SERF 101. It is not only used as high resolution Scanning electron microscope but can be used together with an scanning focused ion beam. Uses include TEM sample preparation and micro-machining. We can also slice and image successively to get tomographic 3D images of small objects from cells to proteins and nano-wires.
