The Thermo Scientific™ Quattro environmental scanning
electron microscope (ESEM) is a versatile, high-performance instrument with a
field emission gun (FEG) for excellent resolution and beam current stability.
Three vacuum modes (high vacuum, low vacuum, and ESEM)
provide the flexibility to accommodate the widest range of samples of any SEM
available, including samples that are outgassing or otherwise not
vacuum-compatible. Quattro offers a choice of detectors that include
directional backscatter information, STEM and cathodoluminescence for tunable
and real color contrast. All Quattro ESEM systems can be equipped with analytical
capabilities, such as energy dispersive x-ray spectroscopy (EDS), wavelength
dispersive x-ray spectroscopy (WDS) and electron backscatter diffraction (EBSD)
coplanar with EDS.
Quattro’s unique architecture is supported by a help function
(User Guidance) that not only instructs, but also directly interacts with the
microscope. Quattro supports undo/redo functionality, scanning presets, column
presets, easy camera-based navigation, SmartSCAN™ and drift compensated frame
integration (DCFI) to boost productivity, data quality and ease of use.
