For members not directly associated with microscopy
below are are some standard abreviations associated with electron
microscopes.
SEM scanning electron microscope.
ESEM is often used for environmental SEM.
Such machines can be fitted with Energy dispersive X-ray
spectrometers (detectors) EDS
An SEM when fitted with Wave Length Dispersive Spectrometers
WDS for X-ray detections and other features to improve beam current
stability the machine is described as an
EPMA Electron Probe Micro-analyser
All the above machines use solid samples.
There are another class of elctron microscope that are regularly used
to study metals which work with very thin samples, in which the
electrons go through the samples these are
TEM Transmission Electron Microscope
or STEM Scanning Transmission Microscope
These are more rarely used in archaeo-metallurgical studies due to the
difficulties involved in sample preparation.
