2.6 Miscellaneous Topics
There are many subjects associated with AFM instrumentation that do
not fall under any of the traditional categories. These include the effect of
vibrations on an AFM, scanning in controlled environments, and heating
and cooling stages.
2.6.1 Vibrations
Vibrations that can degrade the resolution of AFM images can come
from two sources:
a)
Acoustic Vibrations that are transmitted through the air and have
their source from fans, human voices, and other sound sources.
Acoustic vibrations can be reduced by putting the AFM in a sealed
box that is constructed from acoustic dampening materials.
