A family of versatile, high-performance instruments
The Quanta family includes:
- Quanta 250 and Quanta 250 FEG
- Quanta 450 and Quanta 450 FEG
- Quanta 650 and Quanta 650 FEG
Quanta scanning electron microscopes feature three modes (high vacuum, low vacuum, and ESEM) to accommodate the widest range of samples of any SEM system. All Quanta SEM systems can be equipped with analytical systems, such as energy dispersive spectrometer, wavelength dispersive x-ray spectroscopy, and electron backscatter diffraction. 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 for the Quanta 250, 100mm for the Quanta 450, and 150mm for the Quanta 650) 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.
ESEM: Seeing Materials in Motion
By adding variables such as hydration, thermal cycling, and introduction of gas, FEI's ESEM-compatible systems reproduce a variety of conditions needed for carrying out realistic in situ experiments to explore the structure-property-function relationships of materials, from the micro- to the nanoscales.
