Although conventional CCD-based EBSD detectors have been able to analyse metals and alloys with speeds in excess of 1000 indexed patterns per second (pps), the weaker signal and lower symmetries of mineral phases have usually limited data collection from geological samples to significantly slower speeds, often below 100 pps. The release of the groundbreaking Symmetry CMOS-based EBSD detector, together with the powerful AZtec® software, has resulted in a significant improvement in acquisition speeds. Although metal samples can now be routinely measured at speeds in excess of 3000 pps using Symmetry, the fact that extreme pixel-binning of the diffraction patterns is not necessary for high collection speeds means that similarly impressive results are also achievable on rock samples without compromising data quality.
