Description

Bruker’s QUANTAX EBSD analysis system provides the analyst with an easy to use and advanced tool for EBSD measurement and evaluation. The system can also be used in conjunction with the QUANTAX EDS system creating the most advanced integrated EBSD/EDS system, supported by the ESPRIT 2 software under a single user interface.
Fast acquisition with 630 patterns/s (4×4 binning) or 945 patterns/s (8×8 binning) using the e–FlashFS detector
High resolution pattern acquisition with the e–FlashHD, providing pattern images of up to 1600×1200 pixels and an acquisition speed of 140 patterns/s (10×10 binning) and 170 patterns/s (20×20 binning). It supports measurements at low acceleration voltages (down to 5 kV) and low beam currents (down to 0.1 nA).

Specification

e–Flash series – technologically leading EBSD detector architecture

  • Exclusion of unwanted sample parts from measurement through map area definition

Accessories

OPTIMUS™ TKD Detector Head

Bruker’s high performance e-Flash EBSD detector series can now be configured with the OPTIMUS™ TKD detector head which was specifically designed for best sample-detector geometry for on-axis Transmission Kikuchi Diffraction analysis (TKD) in SEM. The detector head not only acquires Kikuchi patterns with unmatched sensitivity, but even provides access to SAED (Selected Area Electron Diffraction) like patterns.

Built-in ARGUS™ FSE/BSE Detection System for e–Flash

The e–Flash EBSD detectors are optionally available with the ARGUS™ forescattered electron (FSE) and backscattered electron (BSE) imaging system. This further increases the versatility of the detectors and provides valuable additional information for meaningful and efficient microstructure characterization.

The set of two BSE detectors is mounted above the screen of the EBSD detector. The three FSE detectors are below the screen. This position of the detectors does not affect the performance or user-friendliness of the e–Flash, the screen remains user replaceable. All electronics required for the operation of the FSE/BSE detectors are already included in the e–Flash+ detector encasement. Apart from the convenience this also ensures that signal loss is minimized as the preamplifiers are close to the detectors.
