Advantages of Certus Optic:

  • Nano piezo scanning XY stage Ratis with clear aperture can position the sample with sub-nanometer accuracy;
  • Nano piezo scanning XYZ AFM head Certus with clear aperture can position the probe with sub-nanometer accuracy;
  • Two scanning modes: XY sample scanning with stage and Z scanning with head scanner, or XYZ probe scanning with head scanner;
  • Plane-parallel scanners (piezo scanning stages) in head and base allows measurements without distortion typical for tube scanners;
  • Study both transparent and non-transparent samples (depending on the microscope type);
  • Optical microscope makes it possible to use all traditional observation techniques for sample studying. So one can easily find appropriate area on the sample and position the tip over it. Certus Optics can be equipped with brand new microscope or adopted for the customers one;
  • Independent systems of sample and probe positioning give a possibility to put the sample in the middle of field of view and install probe over it;
  • Certus Optic can be integrated with spectroscopic devices and can be upgraded to Centaur.

Certus Optic is indispensable tool to study physical and chemical properties of the surface in such areas as:

  • Chemistry;
  • Physics;
  • Biology;
  • Interdisciplinary researches.


Advanced applications:

  • Coatings;
  • Polymers (including liquid crystals and composites);
  • Semiconductors;
  • Biological objects (especially in combination with fluorescent microscopy);
  • MEMS and other electronic components.

In addition, parts of Certus Optic can be possibly used as an independent research equipments:

  • Ratis – positioning of samples (in the plane XY) with an accuracy a few parts of the nanometer;
  • Certus (version - Certus Standard) – a scanning probe microscope to study physical and chemical properties of the surface;
  • Optical microscope – for non-SPM microscopic studies.

Certus Optic can be easily upgraded to our Centaur (HR) SPM-Confocal-Spectroscopy system.

Certus Optic is an essential part of any of the experimental setup for investigation of TERS/FRET effects.

Certus Optic Idea

  • High resolution optical microscope allows easy object detection;
  • Scanning probe microscope alows to obtain object 3D image;
  • Samples can be studied being in native state.
