A new analytical transmission electron microscopy from SELMI company
has been installed in the Lab at the end of 2005 year. This is a highly
automated versatile instrument and operated in an easy intuitive way from a PC with
MS Windows software.
It is equipped with a slow scan 1.4 Mpixel CCD camera from
Kappa for acquisition of reproducible high
quality images. The own software unites the camera and TEM for image processing and storage.
Appropriate design of the specimen holder which accommodates
two samples simultaneously, heated W filament and CCD camera
make it ideal for everyday work.
A range of different polepieces allows
the user to choose a configuration optimized for resolution, tilt, or
contrast. The pumping system is designed to give a clean environment
and is ready for lanthanum hexaboride emitter installation requirements.
Main features are:
observation and photographing of specimen images over a wide range of magnifications;
investigation of specimens through micro diffraction, low-angle diffraction,
and high resolution diffraction; X-ray emission spectroscopy;
investigation of specimens under tilt and rotation;
high contrast mode for medical-biological specimens;
automatic computer control;
computer analysis of images with dedicated software;

This is the previous model of the TEM-125C microscope. The parameters of
this instrument are slightly worse as compared with new one but up to 2005 it
was our main microscope.
It has another type of objective lens and an older electronics.
The objective lens with the upper load of the sample has an advantage
of the rapid change of the microscope operation mode from normal to high
contrast mode, that is useful for biological samples.

This is a rather old microscope. It was installed in the Lab in 1976,
but it still works!!! The main future that does not allow us to retire
it is
the possibility to work in the High Energy Electron Diffraction (ED)
mode. This mode is useful
for precise electron diffraction patterns measurements. Moreover, a large
photographic plate's size is well suited for panoramic imaging.
