Approaching a sharp silicon tip mounted on a cantilever to a sample surface leads to an atomic scale interaction. The result is a bend of the cantilever which is detected by a laser. In static mode the resulting deflection is used to investigate the topography of the sample surface line by line using a feedback loop. In dynamic mode the cantilever is oscillated at fixed frequency resulting in a damped amplitude near the surface. The measurement parameters (setpoint, feedback gain) play a crucial role for image quality. Their effect on the imaging quality is investigated for different nano structured samples.


  • Investigation in static and dynamic mode
  • Modification of numerous parameters to optimize image quality
  • Perform experiment with different samples
  • Excellent price-performance ratio
  • Custom-designed for use in teaching labs
  • Microscope consists of one compact, portable instrument, no additional instruments required
  • Vibration isolated for better and reproducible results


  1. Learn how to mount a cantilever (with tip) and approach the tip towards a sample.
  2. Investigate the influence of the scanning parameters on the imaging quality and performance, e.g. PID gain, setpoint (force), vibrational amplitude, and scanning speed. Use both static and dynamic force mode.
  3. Image different samples (microstructures, carbon nano tubes, skin cross-section, bacteria, CD stamper, chip structure, glass beads) by optimizing the parameters respectively.
