In addition, the field emission gun (FEG) systems contain a S/TEM detector for bright-field and dark-field sample imaging. Another variable that changes amongst the SEM systems is the size of the motorized stage (50mm, 100mm, and 150mm) and the motorized z-range (25mm, 60mm, and 65mm, respectively). The Quanta 650 and 650 FEG are each designed with a roomy chamber, enabling the analysis and navigation of large specimens.
The Quanta SEM line now includes even more flexibility with the release of the Quanta 50 Series. These new instruments, the Quanta 250 , 450 , 650 , and 650 FEG addresss the need to investigate a wide variety of materials and characterize structure and composition. The FEI Quanta™ 50 series provides flexibility and versatility to handle the challenges of today's wide ranging research needs. View any sample and get all the data - surface and compositional images can be combined with accessories for determining material properties and elemental composition.
