Field Emission Scanning Electron Microscopes
Advantages of ULTRA FESEM
Precise and clear imaging
  • Ultra-high resolution BSE imaging
  • Less sensitive to charging effects
  • Compositional contrast imaging
  • Not sensitive to edge contrast
  • Ideal for precise boundary, feature and particle measurements

High Efficiency EsB detector
  • High efficiency direct detection principle for BSE and SE
  • No inefficient conversion plates required
  • Utilises the GEMINI® electron optics for separation of BSE
    and SE
  • BSE imaging at low working distance – 1mm
  • Sensitive for ultra-low voltage imaging – 20 V

Integrated filtering technology
  • Enables true BSE imaging
  • Allows energy selection of BSE
  • Suppresses charging effects of non conducting specimens

Ease of operation
  • Fully integrated detector, no need for adjustment
  • Simultaneous operation with the In-lens SE detector
  • Real time imaging and mixing of BSE and SE signal
  • Easy selection of filtering voltage
