(February 3, 2016 — Peabody, MA) — 
JEOL’s most recent addition to its suite of Transmission Electron Microscopes is the versatile JEM-F200, or “F2,” the only advanced analytical, high throughput 200kV S/TEM in its class to offer a Cold Field Emission Gun and dual Silicon Drift Detectors.
“The combined boost in probe current from the Cold FEG with the dual EDS makes this a fabulous analytical machine,” says Dr. Thomas Isabell, Director of the JEOL USA Product Division. “The ‘F2’ employs the newest in JEOL innovations in an easy-to-use, extremely stable, high resolution imaging and analytical TEM.”
The high brightness/narrow energy spread of the next-generation JEOL Cold-FEG achieves high energy resolution electron energy loss spectroscopy (EELS) for rapid identification of chemical bonding states. The dual Silicon Drift Detectors (SDD) offer the ultimate high sensitivity and throughput for X-ray analysis. Additionally, the new Advanced Scan System employs De-Scan to achieve wide-field STEM-EELs spectrum imaging.
The F2 features a quad lens condenser system that independently controls electron beam intensity (spot size) and convergence angle.
With more versatility and functionality than ever before in a non-aberration corrected TEM, the F2 operation is easier as well. More than 100 beam conditions can be selected at the push of a button, and prior settings can be easily recalled. ECO mode saves power consumption.
A new automated sample holder transfer system, the SpecPorter, makes it easier than ever before to load samples. Once loaded, the PicoStage conducts precise, high speed sample movements of 0.5 nm steps, allowing the operator to move the field of view smoothly over a wide spatial scale range from millimeters to picometers.
“The F2 is a real workhorse with advanced features not found in any other non-aberration corrected TEM,” Isabell says.
