Combined TEM Test Specimen on 3mm grid

Combined TEM Test Specimen - Gold / Graphitized CarbonA holey carbon film is shadowed with gold and graphitized carbon particles are deposited. These particles viewed over the holes may be used for assessment of factors limiting the microscope performance. The evaporated gold forms small polycrystalline islands and within these islands lattice fringes can be resolved.This specimen is also used for contamination measurement rates in the electron microscope by noting the deposition rate of carbon within the holes found in the gold film. |
