Raman spectrometer is mainly applicable for scientific research institutions, institutions of higher learning in physical and chemical laboratory, biological and medical field optics, in the composition of matter determination and confirmation; can also be used in criminal investigation and jewelry industry of drug detection and gemstone identification. The apparatus is known for its simple structure, easy operation, fast measurement and high accuracy, and can be used to obtain a higher resolution, and can be used to measure the UM level of the sample surface.

When a beam of monochromatic light is irradiated to a sample of V0, the molecules can cause the incident light to scatter. Most of the light is only to change the direction of light propagation, and the frequency of the transmitted light is still the same as that of the incident light, which is called Rayleigh scattering; and a scattering light, which is about 10^~10^ of the total scattered light intensity.

In Raman scattering, the scattering light frequency is reduced by the incident light frequency, which is referred to as Stokes scattering. Therefore, the scattering of the frequency increases, which is called the inverse Stokes scattering, and Stokes scattering is usually stronger than the anti Stokes scattering.

The frequency difference between the scattered light and the incident light is called V, which is not related to the incident light frequency, which is related to the structure of the scattering molecule itself. Raman scattering is due to the changes in the molecular polarity of the (electron cloud).

Raman shift is decided to changes in molecular vibration energy level, different chemical bond or a group of molecular vibration, delta e reflects the specified level changes, so with the corresponding Raman shift is characteristic. This is the basis for the qualitative analysis of molecular structures.
