Symmetry is fitted with 5 discrete forescatter detector (FSD) diodes, providing flexible imaging independent of the EBSD detector. All diodes are angled towards the sample for maximum signal detection:
Backscatter position - 2 diodes above screen for optimised atomic number contrast imaging
Forescatter position - 3 diodes below screen for optimised orientation contrast imaging (with false-colour imaging) and topographic contrast. In addition, these diodes provide transmitted darkfield images of electron transparent samples mounted for transmission Kikuchi diffraction (TKD).
Speed - adjustable exposure time providing high quality imaging at more than 106 points per second
