Scan Imaging Technique for Confocal Raman Microscopy

To make extremely fast measurement in a short time, JASCO has developed Surface Scan Imaging (SSI). SSI is used to assess the surface shape of the sample as height information of the stage prior to measurement and Raman measurement is made while adjusting the stage Z-axis according to this surface shape information. Using SSI, a sample with a very uneven surface can be measured to give good Raman spectra with good S/N at all data points. In addition to tablet measurement, the technique makes it easier to analyze a wide range of samples with surface roughness, including rock and concrete, DLC coating, resins, foods, medicines, and fertilizer granules.
