Acronym Definitions
ETD – Everhart-Thornley Detector. This is a secondary electron and back-scattered electron detector used in scanning electron microscopes.
BSE – Backscatter Electron Detection is primarily sensitive to density and atomic number and as such can be used to obtain material contrast.
EDXA – Energy Dispersive X-ray Analysis is an analytical technique used for the elemental analysis or chemical characterization of a sample.
EBSD – Electron Backscattered Diffraction makes it possible to look at the crystal structure and crystal orientation of a sample.
CL – Cathodoluminescence may be used to examine internal structures of semiconductors, rocks, ceramics, glass, etc. in order to get information on the composition, growth and quality of the material.
FIB – Focused Ion Beam microscopy can achieve higher resolution than is typically possible for SEM.
Immersion Lens – A lens that enables higher resolution imaging.
Optiplan Mode – The operating mode used on the Apreo SEM for most imaging with a short working distance using T1 and T2 detectors.
TLD – Through the Lens Detector. Detects secondary electrons to allow for higher resolution imaging.
Low Vac – Low Vacuum mode, used for dry samples, especially ones that cannot be coated using traditional coating methods.
STEM – Scanning Transmission Electron Microscopy. Allows for special techniques to be used not usually possible with conventional SEM or TEM instruments by combining scanning and transmission microscopy.
T1 and T2 – The detectors used for detecting backscattered and secondary electrons on the Apreo SEM.
