Introduction:
Renishaw Micro-Raman Spectroscopy System is a fully integrated confocal microscope spectrometer designed for rapid and routine Raman spectral measurements and analyses. The system includes two laser sources (532nm & 785nm), confocal microscope, filtering optics, an achromatic spectrograph equipped with two gratings, and multichannel CCD (charge-coupled device) detector.
