Description
The JSM-7900F is equipped with a large specimen chamber that accommodates a wide variety of detectors simultaneously, including:
- Secondary and back scattered electron imaging detectors,
- EDS for chemical analysis (Oxford Instruments AZtec Xmax-170),
- EBSD for orientation mapping (Oxford Instruments Aztec HKL Advanced Symmetry System)
- transmission Bright-field and Dark field STEM capabilities
The un-lens Schottky field emission gun (FEG) provides improved brightness, smaller probe sizes with increased probe current for improved analytical performance.
The Super Hybrid lens enables observation of specimens at ultra-high spatial resolution including magnetic and insulating materials.
The new Gentle Beam Super High mode (GBSH) enables a bias voltage of up to 5 kV to be applied to the specimen stage, which decreases charging on nonconductive specimens, improves spot size at low kV, enhances surface topography and further enables high-resolution imaging at extremely low voltages.
Uses / Applications
Applications include imaging and analysis of metals, magnetic materials, semiconductors, ceramics, medical devices, and biological specimens.
