Detector Signal Example
Everhart-Thornley Secondary Electrons

(surface imaging)

Slideshow 1 - True surface imaging conditions demonstrated with an anodized commercially pure titanium sample with the ET detector. Lowering the accelerating voltage stepwise from 1 keV, 500e V to 350 eV demonstrates the differences in the information obtained from the surface.
Backscattered     Electrons (atomic number contrast) Slideshow 2 - Surface imaging capability with backscattered electrons at 2 keV.
Elstar in-lens Secondary Electrons Slideshow 3 - Comparative equivalents of high-resolution secondary (images 1 and 2) and backscattered (3 and 4) electron images demonstrated with anodized commercially pure titanium sample.
Backscattered Electrons
Retractable low voltage, high-contrast solid-   state BSE    detector Backscattered Electrons (atomic number  contrast) Slideshow 4 - Low voltage backscattered imaging of commercially pure titanium.
STEM Transmitted electrons
Bright field/
Dark field /
High Angle Annular Dark Field
Slideshow 5 - STEM (in progress)
ICE Secondary Electrons and Secondary Ions Slideshow 6 - The ICE detector can image using secondary electrons and secondary ions. Oxides are usually visible with Secondary Ions.
