Duobeam Quanta 200i
The ThermoFisher Scientific (formerly FEI/Philips) Quanta™ 3D 200i combines a scanning electron microscope (SEM) with a high current focused ion beam (FIB) to offer a versatile solutions for characterizing and modifying materials that is easy to use and has the flexibility to handle any sample type. The current-boosted tungsten SEM provides excellent imaging capability for sub-micron structures while the high current ion column can be used to precisely prepare samples for 3D nanoanalysis, TEM, EBSD & atom probe imaging or structural modification of sample surfaces at nanometer scale by removing or depositing material at a rapid rate in small defined areas.
The Quanta 3D features three imaging modes – high vacuum, low vacuum and ESEM™ it can accommodate the widest range of samples of any SEM system. A ‘charge neutralization’ mode is integrated for working with FIB on insulating samples.
