Oxford Instruments NordlysS EBSD Detector

An essential part of any EBSD analysis is the acquisition of high quality diffraction patterns. Sometimes the emphasis is on the speed of data acquisition, whilst at other times the data accuracy is paramount. With this in mind, we have developed a fast and versatile detector, Nordlys, to suit all types of EBSD analyses.

Optimised Detector Design

  • Unique Rectangular Phosphor Screen
  • Tapered Nose


  • Improved Spatial Resolution
  • Improved Angular Resolution
  • Optimized Combined EBSD & EDS Mapping
  • Motorized Insertion and Retraction
  • Unique Forescatter Detector (FSD) System
