The FEI Strata DB235 Focused Ion Beam bridges the gap between nanocharacterization and nanomachining by combining a high resolution field-emission scanning electron microscope with a focused ion beam. Uniting these techniques in a single instrument allows users to seamlessly switch from secondary electron imaging to precision ion milling and ion-beam assisted material depostion and selective etching. Four gas injection systems will allow for platinum deposition and selective etching of carbon, metals, and oxides.
