Appendix E: Probes

There are two major types of probes, vibrating mode and non-vibrating mode probes. Each
of these probes may have a coating, which makes them more reflective.
1. Vibrating Mode (VM) Probes
Vibrating mode probes are in the shape of a rect-
angle. Typical VM probe specifications:
Resonance Frequency
Length
Width
Thickness
Force Constant
TM190-A or ACLA probes from Applied Nanostructures recommended.
2. Non-Vibrating Mode (NVM) Probes
Non-vibrating mode probes can be in the shape of
a V or rectangular. Typical NVM probe specifica-
tions are:
Resonance Frequency
Length
Width
Thickness
Force Constant
CM28-A probes from Applied Nanostructures recommended.
