frequency (about 300 kHz) of the cantilever a d the modulation fr quency (several tens
of kHz) for viscoelasticity observation.

In or der to observe a viscoelasticity image correctly, it is essential to af

■ Confirmation before an approach
Affix the specimen, adjust the laser and photodiode, and then perform the coarse
approach according to the procedure in Section 5.4.1, "Approach."
