Raman spectroPhotoMeter

A Raman spectrophotometer irradiates a sample with a laser and measures the frequency shifts in scattered light to obtain molecular vibration information. It is used for material composition identification, structural analysis, and quality control, and is applicable in fields such as chemical engineering, pharmaceuticals, and materials science.
Selection
Select the laser wavelength based on the characteristics of the sample: 532 nm for solid samples and 785 nm for fluorescent samples. Choose the grating density according to resolution requirements: 600 lines/mm for routine detection and 1800 lines/mm for research-grade applications. Configure the microscope or fiber optic probe based on the sample morphology, while also considering adaptability to temperature and humidity.
