Atomic Force Microscope Mechanical Design

Atomic force microscopy afm is a type of scanning probe microscopy spm with demonstrated resolution on the order of fractions of a nanometer more than 1000 times better than the optical diffraction limit the information is gathered by feeling or touching the surface with a mechanical probe.
