Description

The Lumis EBSD detector incorporates the most developed CMOS sensor technology available with advanced optics and accelerating indexing algorithms for the analysis of electron backscatter patterns (EBSPs) using probe currents down to 10 pA and below.

With pattern collection at >2.2 million pixels, the detector is ideally suited to HR-EBSD strain measurement and phase identification applications.

Using optical and sensor binning, the detector can be optimized for high speed EBSD at several thousand frames per second for reduced collection times and higher sample throughputs. The advanced optics and high sensor sensitivity allow EBSPs to be acquired at ultra-low probe currents below 10 pA. This is particularly important for beam sensitive and dose restricted materials, or in cases where higher probe current may introduce contamination or drift.

A large format CMOS sensor and a patented reverse zoom optic to complement and extend the built-in CMOS sensor binning. A high efficiency, octagonal scintillator converts the electron backscatter electrons into light, which is focused on to a user-controlled region of the sensor by the high-quality reverse zoom optic. This allows a continuous choice of "binned" EBSP size and gives full flexibility over EBSP speed, quality and sensitivity.
