Accelerating voltage: The accelerating voltage can be varied by the operator from < 1 kV to 30 kV on all four SEMs. Increasing accelerating voltage will:
• decrease lens aberrations. The result is a smaller probe diameter (when considering it alone) and thus better resolution. Top right [3]: evaporated gold particles at 5 kV and 36 kX magnification; Bottom right [3]: 25 kV at the same magnification.
