Raman spectroscopy is a form of scattering spectroscopy. Raman spectral analysis, based on the Raman scattering effect discovered by Indian scientist C.V. Raman, involves analyzing scattered light with frequencies different from the incident light to obtain information about molecular vibrations and rotations. This method is widely used in molecular structure studies.

When a monochromatic light source with a wavelength much smaller than the particle size of a sample irradiates a gas, liquid, or transparent solid, most of the light transmits in the original direction, while a small portion scatters at various angles. When observed perpendicularly, in addition to Rayleigh scattering with the same frequency as the incident light, there are several weak Raman lines symmetrically distributed with frequency shifts. This phenomenon is known as the Raman effect. The number, displacement, and intensity of Raman lines are directly related to the vibrational or rotational energy levels of molecules. Similar to infrared absorption spectroscopy, Raman spectroscopy provides insights into molecular vibrations or rotations. Today, Raman spectroscopy is widely used for material identification and molecular structure analysis.

The Renishaw inVia Reflex confocal Raman microscope features a fully automated operation system. Its automated functions not only control laser wavelength, filters, and gratings but also perform system alignment, maintenance, and calibration, offering the highest level of automation.

Based on client requirements, GoGo Instruments customized an optical heating/cooling stage for Fudan University, compatible with the Renishaw inVia Raman microscope, to perform variable-temperature Raman testing of metallic materials in humid environments. This product includes a temperature controller, refrigeration controller, and circulating water system. The accompanying PC-based temperature control software simplifies temperature setting and data acquisition, while provided LabVIEW VIs facilitate customized programming.
