A view into the interior of objects can be realized using a transmission electron microscope which produces a two-dimensional image of the specimen. For this purpose, thin slices of the specimens are generally necessary to allow the electrons to penetrate.
 

With the transmission electron microscope LEO 906 (Carl Zeiss Microscopy GmbH) objects can be visualized up to a 60,000-fold magnification using an accelerating voltage of 80 kV. The microscope is equipped with a wide-angle dual speed CCD camera Sharpeye (Tröndle, Moorenweis, Germany), operated by the ImageSP software.
