The
e-FlashHR high resolution EBSD detector from Bruker is the latest
addition to the CrystAlign EBSD analysis system. Featuring a resolution
of 1,600 by 1,200 pixels coupled with high-grade optics, the e-FlashHR
is able to display fine pattern details, making it useful for the
analysis of fine-grained and/or nonconductive materials, nanomaterials,
and for use at low beam current and accelerating voltages.
A
unique mechanism allows in-situ tilting of the detector to help
optimize pattern quality while accommodating both oversize and very
small samples at a variety of working distances. The e-FlashHR also
features a motorized high precision drive which can be software
controlled or operated manually via a touch panel on the side of the
detector. Integrated touch sensors retract the detector immediately
should the probe detect any resistance in movement, and phosphor screens
are easily exchanged by the user.
Running
under Bruker’s ESPRIT software platform, the CrystAlign EBSD system is
able to acquire EDS spectra, HyperMaps and EBSD patterns simultaneously,
significantly speeding up EBSD analysis while providing the ability to
distinguish between phases which create similar patterns. CrystAlign’s
unique pattern streaming process stores the EBSD pattern for each
measured point in a map, allowing live display of the data during
acquisition. The operator can then choose to store all patterns and/or
band positions, phase and orientation, or only the orientation
information. Automatic calibration and analysis routines simplify system
operation, and the system is fully integrated into our ESPRIT EDS
software platform.
