High Resolution Raman Spectrometers - LabRAM HR 800

Technical characteristics:

The HR800 produced by HORIBA JOBIN YVON is an integrated Raman system, high stability bench-top for reproducible Raman measurements at high, medium or even low spectral resolution. The microscope is coupled confocally to a 800 mm focal length spectrograph equipped with two switcheable gratings.

  • High spectral resolution (0.3 cm-1/pixelat 633 nm);
  • Large spectral range of Raman shift from  30 to 4000 cm-1 ideal for organic and inorganic species;
  • Unique adjustable angle notch filter technology;
  • LabSpec Software for control the instrument, data acquisition, data manipulation and mapping option;


LabRAM HR 800 Raman Spectrometer  is a powerful optical technique for materials study and characterization based on  inelastic scattering of light due to light-matter interaction during which the energy of the incident laser will be shifted. This energy loss is characteristic for a particular bond in the molecule. The Raman spectrum  provide qualitative and quantitavie information: peak position is determined by chemical species;  line intensity is proportional to concentration; shift in position of the peak indicate the stress and temperature effect and the width the structural disorder.



LabRAM HR 800 Raman Spectrometer  can be used  for the analysis of solids, liquids and solutions for:

  • chemical identification, characterization of molecular structures;
  •  to determine the composition and phase (crystalline/amorphous) of composites materials;
  • environmental stress on a sample and  crystal quality and composition of alloy semiconductors;
  •  nature of oxides on compound semiconductors;
  •  polymers characterizations and polimer nanocomposites;
  • chemical and biological detection using SERS technique;
  • micro/nano structures characterization ( micro/nanorods,  carbon nanotubes), self assembled molecule (SAM) on functionalized substrate and other.
