The Nano-Observer Atomic Force Microscope is a flexible and powerful AFM microscope. It is one of the most cost effective instruments on the market offering high levels of performance at a highly competitive price.

Compact and robust, the Nano-Observer fulfils the requirements for advanced users or beginners. It avoids laser alignment with a pre-positioned tip system. A top and side view of the tip/sample, combined with vertical motorised control, makes the pre-approach easy. Easy positioning can be achieved by combining the optical access with the X-Y translation stage.

Ease of use

Top view for tip/sample positioning

A video color camera is provided with the AFM offering an helpful viewing from the top for tip/sample positioning or side view to make the tip/sample approach easier.



Side View

  • Sample/tip visibility
  • Ease of use
  • Avoids damaging sample or tip
  • Better contrast by lateral illumination


High performance optic (option)positioning

A video color camera is provided with the AFM offering an helpful viewing from the top for tip/sample positioning or side view to make the tip/sample approach easier.



Intuitive software

Only main parameters are displayed for a clean and simple interface software

  • AFM Mode choice in one click
  • Autoset of the controller ! (no cables or module to mount or remove)
  • Pre-configured software (auto settings of most of the parameters)
  • AFM adjustment by “Steps” : the user can follow defined “steps” to set easily the AFM.
