Angstrom Advanced Atomic Force Microscope and Scanning Force Microscope Software


The Software is available with the following data types of images:

AFM Contact Mode:

  • Topography — the rise and fall of the sample surface.
  • Deflection — cantilever flexes because of the rise and fall of sample topography and the amount of this deflection can
  • be reflected by the photodetector’s Up-Down signal.
  • Friction — lateral forces between tip and sample, which causes the torsion of the cantilever and can be reflected by the photodetector’s Left-Right signal.

AFM Tapping Mode:

  • Topography — the rise and fall of the sample surface.
  • Amplitude — cantilever oscillating amplitude changes because of the rise and fall of sample topography.
  • Phase — cantilever oscillating phase changes because of the sample material characteristics.


Scanning Tunneling Microscope:

  • Topography —the rise and fall of the sample surface.
  • Current — Tunneling current changes between tip and sample surface.

Our goal is to provide our customers with the best products with highest standard of service at cost efficient pricing.
