The JEOL JSM-7500F is an ultra high resolution field emission scanning electron microscope (FE-SEM) equipped with a high brightness conical FE gun and a low aberration conical objective lens).
The improved overall stability of the JSM-7500F enables you to readily observe your specimen at magnifications up to 1,000,000x with the guaranteed resolution of 1 nm.
The energy filter (r-filter) makes it possible to observe the fine surface morphology of nanostructures.
The unique Gentle Beam (GB) mode decelerates incident electrons just before they hit the specimen to reduce the incident-electron penetration and the charging in the specimen. The GB mode provides high-resolution images whose quality is as high as those of higher accelerating voltages, even at low accelerating voltages from 100 V to 3 kV without damaging the specimen surface.
