Make & Model
:nVia Raman from Renishaw
Spatial resolution of ~1 µm
Raman shifts within 150 cm-¹ of the excitation frequency can be measured at excitation wavelengths of either 488 nm, 532 nm, 785 nm, with a spectral resolution of ~1 cm-¹.
Working Principles

When monochromatic radiation is incident upon a sample then this light will interact with the sample in some fashion. It may be reflected, absorbed or scattered in some manner. It is the scattering of the radiation that occurs which can tell the Raman spectroscopist something of the samples molecular structure. If the frequency (wavelength) of the scattered radiation is analyzed, not only is the incident radiation wavelength seen (Rayleigh scattering) but also, a small amount of radiation that is scattered at some different wavelength (Stokes and Anti-Stokes Raman scattering). (approx. only 1 x 10-7 of the scattered light is Raman). It is the change in wavelength of the scattered photon which provides the chemical and structural information.

Applications

It is applicable for the chemical identification of elements and compounds ,study of thin films, graphenes , CNT, quantum dots, polymer structures, coatings, microelectronic integrated circuits, mineral inclusions, biological tissues, and others.
