Symmetry: EBSD Detector

EBSD – electron backscatter diffraction – is a powerful microanalysis technique that enables rigorous characterisation of the microstructural properties of crystalline materials. A -performance EBSD is critical for the effectiveness of the technique, influencing both speed and data quality.

Symmetry is a revolutionary new EBSD from Instruments based on customised CMOS technology, providing unprecedented performance and ease of use:

  • Over 3000 indexed patterns per second (pps)
  • Up to 30x faster than existing CCD-based detectors
  • Extreme sensitivity for current and kV analyses
  • 1244 x 1024 pixel resolution, ideal for HR-EBSD applications
  • resolution patterns at all speeds
  • Innovative features for simple operation

Symmetry: one for all applications with no compromise.

CMOS SPEED

CMOS SPEED

Operating at over 3000 patterns per second, Symmetry is the world’s fastest EBSD . This step-change in performance delivers not only for routine applications, but also for large area mapping, 3D EBSD and in situ experiments.

CMOS SENSITIVITY

CMOS SENSITIVITY

With unparalleled sensitivity and dynamic range, Symmetry is ideal for even the most challenging applications, where beam currents coupled with fast, -resolution patterns are a necessity. Now there’s no compromise between speed and sensitivity.

SIMPLICITY

Symmetry is a game-changer. Its unprecedented all-round performance will open up exciting new developments in even the most exacting of applications.

Speed & Sensitivity

SYMMETRY CMOS v CCD: SPEED

BREAKTHROUGH TECHNOLOGY

CMOS-based cameras can be both fast and sensitive and are already making a significant impact in other technology fields. Symmetry incorporates a customised CMOS image sensor, optimised for EBSD. It enables a level of performance never achieved by any previous EBSD . Whether the focus is on speed or sensitivity, there is no need for compromise.

SYMMETRY CMOS v CCD: APPLICATIONS

THE ‘ONE CHOICE - NO COMPROMISE’ DETECTOR

The unrivalled combination of speed and sensitivity of Symmetry ensures the best performance across a complete range of samples. acquisition speeds can be achieved without any loss of data quality. Symmetry’s sensitivity means that, even on more challenging samples such as complex or films, an order of magnitude increase in acquisition speed may be achieved with the best possible data quality.
