Microscopic confocal Raman spectrometer is an analytical instrument that combines microscopy technology with Raman spectroscopy. It generates Raman scattering by laser excitation of the sample and detects the scattering spectrum to analyze the composition and structure of the substance.
By using confocal microscopy technology, laser can be focused onto small areas (such as nanoscale) to achieve high-resolution detection of sample surfaces, suitable for microscopic analysis of inclusions in complex substances.
By analyzing the frequency changes of Raman scattering spectra, information such as chemical bonds and molecular vibrations of substances can be obtained, which can identify the structure of substances like "fingerprints" and are widely used in fields such as materials science and biology.
The confocal microscopy Raman spectrometer combined with confocal microscopy technology and Raman spectroscopy analysis has high spatial resolution and non-destructive testing characteristics. This instrument excites the sample through laser and collects Raman scattering signals to obtain molecular structure information of the substance.
The working principle of confocal Raman spectrometer is mainly based on Raman scattering effect, which is a non-destructive testing technology for substances. When laser is irradiated on the surface of a material, it scatters a portion of light, most of which has the same frequency as the incident light. This portion is elastic scattering light, while another small portion has a frequency different from the incident light. This is because the laser exchanges energy with the sample molecules, producing inelastic scattering light, known as Raman spectroscopy. By studying Raman spectroscopy, information such as the structure and properties of substances can be obtained.
The instrument also combines confocal technology, which enables it to scan the sample in three-dimensional space and obtain three-dimensional Raman spectroscopic information of the sample.
