Atomic number reference sample

Calibration sample designed for quantitative BackScatter Electrons (BSE) and Electron Beam Absorbed Current (EBAC) techniques. A range of materials are included to provide calibration over a wide range of atomic numbers, and a Faraday cup is included for full quantitative workflows.


  • SEM stub with Faraday cup and reference materials
  • Series of reference sample have increasing atomic number
  • Surfaces of reference materials are polished for pure compositional contrast


  • Easy sample for training on the quantitative techniques
  • Enables calibration of detector signals to atomic number
  • Measure beam current with excellent Faraday cup
