  • Description

    TEM is used to analyze micro-structures of materials with high spatial resolution. The high voltage electron beam generated from electron gun is illuminated on thin film specimen. The beam penetrating the specimen passes through an array of magnetic lenses and forms a high resolution electron image of the electron diffraction pattern.
