Field Emission Scanning Electron Microscope

Model: JSM-7600F Schottky Field Emission Scanning Electron Microscope

Make: Jeol company, Japan

Features:

  • Semi in-lens SEM with high resolution: The adoption of a High Power Optics irradiation system delivers high-resolution, high-speed, high-accuracy element analysis. The incorporation of the Gentle Beam enables top-surface imaging of a specimen at very low energies of several hundred eV. Semi-in-lens provides high-resolution observation and analysis. High resolution observation and high spatial resolution analysis is achieved through the combination of a semi-in-lens type objective lens that can collimate the electron beam even at low accelerating voltages, and the in-lens Schottky electron source that provides a stable current over a long service life.
  • Gentle Beam (GB) provides top-surface imaging with ultra-low energy incident electrons A Gentle Beam (GB mode) with better resolution than the normal mode is available. In GB mode a bias voltage is applied to the specimen while the electron beam is emitted, allowing top-surface imaging with only several hundred eV of incident electron, making it possible to obtain high resolution images of samples that have been difficult to observe until now.
  • High Power Optics delivers high-speed, high-precision analysis. High Power Optics are adopted for the optical system, providing not only high-resolution imaging, but also stably delivering high-speed, high-precision analysis, including element analysis.
