Applications include imaging and analysis of metals, magnetic materials, semiconductors, ceramics, medical devices, and biological specimens. 


The JSM-700F 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,
  • 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 tomography; and further enables high-resolution imaging at extremely low voltages. 


  • Resolution: 7Å @ 1 kV, 6Å @15 kV, 6 Å in STEM
  • Analytical resolution sub 30 nm scale

  • High sensitivity BE detector providing exceptional performance at low accelerating voltages
  • Ultralow kV in-lens detectors
  • GBSH-S (GENTLEBEAMTM Super High mode) enabling high resolution imaging at extremely low accelerating voltages (down to 10V)
  • In-lens Schottky Plus field emission electron gun and low aberration condenser lens provide high levels of brightness
  • Super Hybrid Lens (SHL), a combination of electrostatic and electromagnetic lenses, to support ultra high resolution imaging and analysis of various samples ranging from magnetic materials to insulators
  • Ample prove current is available at low accelerating voltage, supporting various applications from high resolution imaging to high speed elemental mapping
  • A new sample exchange system is designed to change samples in a safe, speedy, seamless manner through simple operations
  • Oxford Instruments Aztec Live Energy Advanced Xmax170 X-Ray EDS System
  • Oxford Instruments Aztec HKL Advanced Symmetry EBSD System
