規格：FESEM Schottky Thermal FEG
JSM-7900F is JEOL’s new flagship FE-SEM which combines extreme high resolution imaging, enhanced stability and exceptional ease of use for any level of operator in multi-purpose environment.
Neo Engine（New Electron Optical Engine）
Newly developed functionality that integrates lens control system and automatic technology, "Neo Engine" (New Electron Optical Engine) is a standard feature. Even though electron optical condition is changed, there is neglegible change in beam alignment, allowing for fast and easy image acquisition at any accelerating voltage and probe current.
①Improvement of automation function

GBSH-S(GENTLEBEAM™ Super High resolution Stage bias mode)
GBSH is a method which improves spatial resolution at any accelerating voltage.
New Backscattered Electron Detector
The newly developed ultra high sensitive backscattered electron detector provides us clear contrast image. Detector sensitivity is highly improved and high compositional contrast image can be observed at low accelerating voltage.
New appearance design implements compact footprint.
New Sample Exchange method
Newly designed sample exchange system (load lock type) is applied.
SMILENAVI is an operation navigation system designed to assist novice users to quickly and efficiently learn the basic operation of the instrument.
When you hover the mouse pointer over a button on SMILENAVI, a frame is displayed on the corresponding button on PC-SEM.
When a button on SMILENAVI is clicked, the screen is grayed out except the corresponding button on PC-SEM.
When a button of hardware key on SMILENAVI is clicked, the picture of operation panel and the hardware key are displayed.
There are videos explaining operations.
In-Lens Schottky Plus Electron Gun
In-Lens Schottky Plus Field Emission Electron Gun implements higher brightness by improving combination of electron gun and low aberration correction condenser lens.
ACL (Aperture Angle Control Lens)
ACL is attached above the objective lens and optimizes electron beam convergence angle in all range of probe current automatically. Hence, probe diameter is always minimized because illuminated electron beam’s convergence angle is adjusted automatically even though probe current amount is changed. It’s possible to collect both high resolution images and microanalytical data smoothly even though probe current is widely changed.
Super Hybrid Lens
JEOL’s developed superimposed electrostatic / magnetic field lens type objective lens, "Super Hybrid Lens" as standard, provides us ultra high spatial resolution observation and analysis for any type of samples including magnetic and non-conductive sample.
Maximum 4 detectors’ simultaneous signal acquisition is available.
High Spatial Resolution Observation
GBSH (GENTLEBEAM™ Super High resolution mode) provides us high spatial resolution images at ultra low accelerating voltage.
High spatial resolution observation
Low vacuum function
Low vacuum function can provide us observation and analysis of non-conductive sample without conductive coating easily and with high spatial resolution.
