This test specimen is most useful to determine the rotation between a diffraction patter and the selected area image.

A Diffraction Standard for the calibration of the camera length of a TEM. The standard is composed of a thallium chloride film evaporated on a 3.05mm TEM-grid. The very small crystallite size yields ring patterns suitable for calibration.

A Diffraction Standard for the calibration of the camera length of a TEM. The standard is composed of a 30nm thin aluminum film evaporated on a holey carbon film sitting on 400mesh copper TEM-grid. The very small crystallite size yields ring patterns suitable for calibration.

A holey carbon film is shadowed with gold and graphitized carbon particles are deposited on a 3.05mm grid. These particles viewed over the holes may be used for assessment of factors limiting the microscope performance.
