MIRA\\ LMU-CS

High Resolution Schottky FE SEM

The Most Important Features:

  • High brightness Schottky emitter for high-resolution / high-current / low-noise imaging.
  • A unique three-lens Wide Field Optics™ design offering the variety of working and displaying modes embodying the Tescan proprietary Intermediate Lens for the beam aperture optimization.
  • Real time In-Flight Beam Tracing™ for the performance and spot optimization integrating the well established software Electron Optical Design.
  • Unique live stereoscopic imaging with 3D Beam Technology.
  • First class YAG-based detectors for fast imaging rate.
  • High-throughput large–area automation, e.g. automated particle location and analysis.
  • Extraordinary analytical potential – 11 chamber ports with optimized analytical geometry allowing simultaneous EDS, WDS or EBSD
  • Fully automated microscope set-up including electron optics set-up and alignment.
  • Sophisticated software for SEM control, image acquisition, archiving, processing and analysis.
  • Network operations and built-in remote access/diagnostics come as a Tescan standard.
