Magnification Calibration
• Use “graphite” or any crystalline samples having known lattice spacing
• Use the FFT method.
It is very important to make sure DigitalMicrograph software correctly reads
the TEM magnification. If the communication between the computer and the
TEM is established, the magnification is read automatically. Otherwise, please
make sure DigitalMicrograph is set to prompt the user to enter a value for TEM
magnification every time an image is to be acquired. This can be set by
choosing the “Global Microscope Info” window shown in Figure 2-5 under the
Microscope menu (Figure 2-6).
