Installing the cantilever
To maximise ease of use, the Nanosurf easyScan 2 AFM is designed so that
the cantilever can be installed and removed without having to readjust the
cantilever deflection detection system. This is possible because an align-
ment system is used that consists of an alignment chip and matching
grooves in the back side of the cantilever chip. This positions the cantilever
with micrometer accuracy (see figure
Cantilever , left ). Note though, that
this accuracy is only guaranteed when the cantilever and the mounting chip
are absolutely clean. Installation of the cantilever should therefore still be
carried out with great care because good results depend strongly on the
accuracy of this process.
Selecting a cantilever
Now select the proper cantilever type for the measurement mode you wish
to use. The stiffer, short NCLR cantilever is generally used for the dynamic
