August 7, 2008 (Peabody, Mass.) -- JEOL USA demonstrated a new Thermal Field Emission Scanning Electron Microscope, the JSM-7600F, at M&M 2008 in Albuquerque, New Mexico. The new SEM integrates a semi in-lens system for high resolution imaging with an in-lens thermal electron gun. A new Graphical User Interface enables easy navigation through imaging and analyzing procedures.

In-lens Thermal Field Emission Gun

JEOL’s proven in-lens thermal electron gun, combined with a patented aperture angle optimizing lens, achieves a probe current of 200 nA or higher at an accelerating voltage of 15 kV, efficiently acquiring high quality data in elemental analysis. The JSM-7600F is capable of high resolution high sensitivity analysis under any combination of operating conditions for various samples and research requirements, with guaranteed resolution at high accelerating voltage of 1.0 nm (30 kV; WD 4.5 mm), guaranteed resolution at low accelerating voltage of 1.5 nm (1 kV; WD 1.5 mm), and guaranteed resolution at high probe current of 3.0 nm (probe current 5 nA, accelerating voltage 15 kV, WD 8 mm).

High Performance Analytical Instrument

The JSM-7600F is a powerful tool combining high resolution imaging and high speed analysis. Utilizing the electron beam finely focused at low accelerating voltage and high probe current, the microscope, when outfitted with an EDS detector, can rapidly acquire high resolution X-ray mapping data. The JSM-7600F incorporates a through-the-lens detection system that features a new energy filter, r-filter, designed to vary the mixture rate of secondary electron and backscattered electron images, enhancing the topography or compositional differences of images as needed. Gentle beam mode improves low kV image resolution.

New Easy to Use Operator-oriented User Interface

The user interface is designed to collectively define, save, and retrieve photographing and imaging conditions to facilitate data acquisition under optimum conditions. It also supports simultaneous acquisition of 4 different types of images, significantly improving throughput. 5-Axis Motor Stage and Intuitive Specimen Movement with Track Ball

The standard 5-axis motor drive eucentric stage controls sample movement seamlessly throughout the magnification range from 25x to 1,000,000x. Intuitive specimen control by the track ball assures smooth movement of the area of view in high magnification imaging.

Versatile specimen chamber for optimum analysis

The JSM-7600 specimen chamber accommodates samples up to 200 mm in diameter, and features a complete set of detector ports secondary electron detector, backscattered electron detector, EDS, WDS, EBSD, and cathode luminescence detector, allowing the user to select an arrangement optimum to their analytical objectives.
