PREPARING FOR MEASUREMENT

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
