The advantages of the Dynamic Contact Module II (DCM II) are:
• Improved resolution in both force and displacement.
• Decreased sensitivity to environmental noise.
These two advantages enable you to make meaningful measurements of
mechanical properties at displacements as small as 10
nm. The table
below shows the specifications for the DCM
II.
