Premium BSE detector

Highest performance four-quadrants BackScattered Electron (BSE) detector

Benefits

  • Navigate with live BSE imaging to localise grains of specific composition or crystallographic orientation
  • Image coating free surfaces by reducing charging with high scanning speeds and signal averaging
  • Measure changes in atomic number/Z-contrast across the sample
  • Distinguish between materials and topographic contrast
  • Produce colour images by mixing multiple signals
  • Measure height with the optional topographic reconstruction

Features

  • Dedicated Si sensors for highest speed, down to 10 ns/pixel
  • Improved low-kV sensitivity, down to 1 kV accelerating voltage
  • In situ preamplification for minimum noise and maximum speed
  • Simultaneous four channels for topographic/compositional contrast
