  • Multiple simultaneous signal recording (confocal, spectra, topography, phase etc.);
  • Recording of full spectrum in each scan point (hyperspectral imaging);
  • Integration with unmodified upright or inverted optical microscopes to work with transparent and opaque samples;
  • Modern cross-platform software (for all the Centaur units).

Components:

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

 

Demonstration of obtaining the spectral data from surface with carbon nanotubes:

 

 

Carbon nanotubes (CNTs) on glass surface. Confocal Raman image. One layer scanning.

Image size 25х25 μm. 100х100 points. Exposition time at point - 0,05 sec.

Images was obtained with AFM-Raman-Confocal system Centaur in confocal Raman microscope mode.

The sample was provided by Prof. V.K.Nevolin (www.nanotube.ru).
