Fast Scan direction
[ OMCL-AC series ]
When you set your sample to your instrument, please consider the unique shape of the Tetra tip and choose the direction of the sample.
When measuring long grooves, you can get an idea of what angle of the cut will be quickly by aligning the cantilever along the grooves and scanning across at right angles against grooves (see below). In AC mode AFM measurement, you don't need to choose the fast scan direction along the cantilever axis as in the contact mode AFM measurement. You can leave the stick-slip problem out of consideration.
