High resolution transmission electron microscope with computer control TEM-100K

It is used for investigation of microstructure and phase composition of specimenes.

Basic functions:
  • Observation and photographing the images of specimens in a wide magnification range;
  • Investigation of specimens in micro diffraction, low-angle diffraction, high resolution diffraction;
  • Investigation of specimens at their tilt and rotation;
  • High contrast mode for medical-biological specimens;
  • Automatic computer control;
  • Computer analysis of images by special programs;
  • Elementary analysis of investigated specimens.
