Electron microscopic examinations in the service area
Electron microscopy is preferably used for structural investigations when the resolving power of light microscopy is no longer sufficient, i.e. when specimens with structural details on the order of less than one micrometer are to be examined. However, electron microscopic studies may also be of interest on larger objects, such as those whose imaging requires a high depth of field. Analytical techniques (energy dispersive X-ray spectroscopy (EDXS) and electron energy loss spectroscopy (EELS)) allow the chemical composition of the sample to be analyzed. Chemical analyses can be performed with exceptionally high spatial resolution at the nanometer scale, allowing samples that are chemically inhomogeneous at the nanometer scale to be characterized. In principle, material science and biological specimens can be analyzed in the broadest sense. A wide range of preparation methods is available for sample preparation.
Two types of electron microscopy are used in the LEM: scanning electron microscopy (SEM) to study surfaces and transmission electron microscopy (TEM) to study structures inside samples. Examples can be found under the keywords transmission or scanning electron microscopy. Nanostructuring can be performed with a combined focused ion beam (FIB)/REM system, which is also used for target preparation of TEM samples.

Instructions for accessing the LEM sFTP server
The images and results of the service examinations performed by the Electron Microscopy Laboratory are available to customers via an sFTP server. Instructions for accessing this server can be found at the following link.
To access the server, an account with a personal password is required. If this is not available, our service staff will help you to set it up.
