Section thickness vs. Image quality breakdown point. The latter is the accelerating voltage in kilovolt (kV) at which the quality of the image starts to degrade for a certain section thickness in nanometer (nm). Higher accelerating voltages yield worse image quality.
| Thickness [nm] | Image quality breakdown point [kV] |
|---|---|
| 50 | 1.5 |
| 100 | 2 |
| 200 | 3 |
| 300 | 5 |
| 500 | 10 |
