Symmetry S2 is the only genuine all-in-one EBSD detector on the market, and is based on the revolutionary Symmetry detector, the world’s first EBSD detector to utilise advanced CMOS technology. Exceptional performance for all EBSD applications is combined with ease of use and a range of innovative design features. Highlights include:
Guaranteed indexing speeds in excess of 4500 pps
1244 x 1024 pixel resolution – ideal for high angular resolution (HR) EBSD
Unique fibre-optic coupling with sub-pixel distortion
Extreme sensitivity, benefiting all types of analysis
Software controlled detector tilting
Symmetry S2 uses a customised CMOS sensor and fibre optics to unlock a unique and powerful combination of speed, sensitivity, and diffraction pattern detail. Symmetry S2, in combination with the AZtec software, delivers exceptional performance on all materials and for all measurements. The highest analysis speed of Symmetry S2, in excess of 4500 pps, enables texture and grain size characterisation in a matter of seconds, yet this is achieved without requiring high beam currents or sacrificing pattern resolution. This means that these high speeds can be achieved even on challenging, real-world samples such as multiphase light metal alloys or deformed steels.
In addition, Symmetry S2 can collect distortion-free, megapixel resolution EBSPs for detailed strain and phase analyses. This is a detector to suit all applications, enhanced by innovative features such as software controlled tilting (with dynamic calibration) and a unique proximity sensor.
When an EBSD detector has no compromise, no application is beyond your reach.
The Symmetry S2 detector has an outstanding performance coupled with ease of use, making it the ideal detector for all EBSD applications:
The performance of the Symmetry S2 detector is enabled by the powerful AZtecHKL acquisition platform, backed up by the fastest and most modern EBSD data processing software, AZtecCrystal.

Methylammonium Lead Halides (MALHs) are organic crystal compounds used in solar cells, LEDs, LASERs and photodetectors. Recent improvements to EBSD detectors now allows for their characterisation of grain size and texture.
Martensitic structures are traditionally challenging to measure with EBSD. Here, the sensitivity and pattern detail provided by Symmetry enables exceptional results from a martensitic stainless steel.
CMOS-based EBSD detectors enable faster and more sensitive analyses of samples. Sensitivity is related to the full-system efficiency, or Detective Quantum Efficiency (DQE).
CMOS-based EBSD detectors enable faster and more sensitive analyses of samples.
The Symmetry S2’s combination of extreme speed, sensitivity and versatility makes it the only EBSD detector that can cover all application areas. This includes:
