Сentaur I - Scanning AFM/Confocal/Raman/Fluorescence system for Raman/Fluorescence and AFM/Raman (TERS) imaging

Centaur I - Scanning AFM/Confocal/Raman/Fluorescence system for Raman/Fluorescence and AFM/Raman (TERS) imaging

 

Centaur combines:

  • Scanning Probe Microscope;
  • Inverted or Upright Optical Microscope;
  • Laser Confocal Microscope;
  • Raman Confocal Microscope;
  • Fluorescence Confocal Microscope.

 

Centaur - SPM, Confocal, Raman, Fluorescence System

Applications:

  • Scanning Probe Microscopy;
  • Raman Confocal Microscopy;
  • Fluorescence Confocal Microscopy;
  • Near-Field Scanning Microscopy;
  • Tip-Enhanced Raman Spectroscopy (TERS);
  • Tip-Enhanced Fluorescent Spectroscopy (TEFS).

 

Where to use:

  • Chemistry. Combination of methods of scanning probe microscopy and Raman spectroscopy allows the analysis of the composition and structure of organic and inorganic substances, traditional and composite materials;
  • Physics. Investigation of physical characteristics of surface and subsurface layers of substances and materials;
  • Biology. Study of tissues, cells and their structures, biological molecules and the interactions between them;
  • Interdisciplinary research. Research in the field of nanotechnology, pharmaceuticals, materials science, mineralogy, geology, forensic, analysis of art and many others.


Centaur - structural scheme

Advantages of Centaur:

  • Dual independent scanners (in head and base);
  • Multiple simultaneous signal recording (confocal, spectra, topography, phase etc.);
  • Full spectra recording in each scan point (hyperspectral imaging);
  • Integration with virtually unmodified upright or inverted optical microscopes to work with transparent and none transparent samples;
  • Modern cross-platform software (for all the Centaur units).

 

Centaur - basis unit (AFM, optical microscope, confocal unit, spectrometer)

Components:

  • Scanning Probe Microscope Certus;
  • XY - sample piezo scanning stage Ratis;
  • Confocal unit;
  • Monochromator;
  • Optical microscope (upright or inverted);
  • Digital controller EG-3000;
  • Software NSpec.
