©2020 Biological and Chemical Oceanography Data Management Office.The Raman microscope is a laser-based microscopic device used to perform Raman spectroscopy. The Raman microscope begins with a standard optical microscope, and adds an excitation laser, laser rejection filters, a spectrometer or monochromator, and an optical sensitive detector such as a charge-coupled device (CCD), or photomultiplier tube, (PMT). One example is the XploRA confocal Raman microscope (information from the manufacturer).

|---|---|---|
| IODP360 - Raman spectra of a core sample taken at the Atlantis Bank | Raman spectra were collected using a Horiba LabRam HR confocal Raman system using a blue laser with a wavelength of 473 nm, a 600 grooves/mm grating, and a 50x objective. The slit size was 150 µm and the confocal hole diameter was 1mm. This setting was chosen to minimize oxidation of the Fe-Mn oxide that was intergrown with the organic inclusions. | Horiba LabRam HR confocal Raman system |
| Raman spectra from several different bivalve species; analysed in the North lab at UMCES HPL from 2012-2014 (Raman Spec Bivalves project) | Raman spectra were acquired with an XploRA confocal Raman microscope by Horiba Jobin Yvon, Inc. The system includes a flat field spectrograph with a multichannel air cooled CCD detector and color camera optically coupled to an Olympus BX41 microscope. The investigators used three lasers: a 532 nm 25 mW solid-state laser, a 638 nm 25 mW laser diode, and a 785 nm 25 mW laser diode. See more information about the Raman microscope on the UMCES website. | XploRA confocal Raman microscope |
