What is the basis of laser irradiation conditions in Raman spectroscopy? What kind of spectrum can be obtained and what kind of optical microscope image will be obtained if the sample has burnt? By setting the conditions correctly, you can shorten the measurement time and obtain a clear Raman image and spectrum. Concept of laser irradiation condition The conditions are determined so that a high-S/N ratio Raman spectrum can be obtained in a short time measurement. Especially for Raman imaging, this condition is important because it determines the time it takes to acquire an image. The following shows how to determine the conditions for laser wavelength, power, exposure time, and…
