BSE Acquisition

With quantitative backscattered electrons (qBSE), it is possible to map the material density and to characterise distribution of phases with high spatial resolution. qBSE is generally applied to flat polished samples, but may also be applied to 3D surfaces when combined with Electron Topography for Geometrical Analysis. It may also be used for phase identification in systems of known constituents. It enables researchers to gain quantitative insights into material properties, such as crystallography, phase distribution, and atomic composition.

The qBSE system allows to unveil atomic number/Z-contrast invisible in SE techniques, create high-resolution material density maps, perform Electron Channelling Contrast Imaging (ECCI) and orientation contrast (OC), characterize hot samples, including those exceeding 1,000ºC, and capture 4k color images for SEM movies.

The system consists of hardware,softwareand selectable options.

Reveal Z-contrast

• Reveal soil structure and identify mineral constituents
• Determine variations of content in biological structures
• Image shape, size and distribution of nanoparticles

Electron Channel Contrasts

• Identify dislocations, stacking faults and grain boundaries – in the SEM
