In Raman microscopy, also called confocal Raman microscopy, an optical microscope and a Raman spectrometer are combined into one instrument in order to provide high resolution images of small samples. This high resolution imaging has applications that include materials science, earth science, cell biology, medicine, cosmetics, and art analysis.
A Raman microscope consists of a basic optical microscope, a Raman spectrometer, a laser, a light source, and a detector such as a CCD camera. The optical microscope uses light to magnify and identify samples while the Raman spectrometer scatters light and measures the excitation vibration. When selecting a microscope, it is important to consider the qualities of each of the microscope's components and their optimal configuration for a particular application.

Features - Characterization and identification of small particles
- Great for ID of particulate contaminants
- High-resolution depth profiling and subsurface analysis on transparent and semi opaque samples Excellent for characterizing coatings, multi-layer laminates, thin films, inclusions and subsurface defects
- Organic and inorganic samples—the wide spectral range with measurements down to 50cm-1 is of particular advantage for inorganics, which typically have bands at low frequencies
- Molecular morphology characterization—good representation of carbon and silicon molecular backbones provides great differentiation of pharmaceutical and mineral polymorphs as well as differentiation of amorphous and crystalline forms of silicon and different carbon nanomaterials
- Characterization of surface areas and subsurfaces are supported with x-y area maps and x-z maps
- Measurements through glass and plastic packaging—allows measuring directly through evidence bags, injectable ampules, and protective overcoatings
- Remote sampling for samples too large to fit under the microscope, with optional fiber-optic probes
- Configurable GO button on instrument provides for walk-up operation
- All data collection, processing, and reporting steps can be stored so that a user can load a sample under the microscope, push a button, and have a report print out with no interaction with the computer
- Supports surface-enhanced Raman scattering (SERS) measurements
- Lasers, filters, and grating Smart modules all user exchangeable and can be shared with other DXR instruments
- Spatial resolution—demonstrated as good as 540nm resolution on ideal sample
- Confocal depth resolution—demonstrated as good as 1.7µm on ideal sample
- Full spectral range of 3500-50cm-1 captured with a single exposure of the CCD avoids stitching artifacts. Extended spectral range to 6,000cm-1 available for 532nm laser
- Supports multiple excitation lasers. 532nm, 633nm, and 780nm
- Automatic fluorescence correction available with all excitation lasers
- Research-quality Olympus viewing optics
- Automatic intensity correction generates spectra that are comparable between instruments and different excitation lasers
- Multidimensional wavelength calibration provides accurate wavelength calibration across entire spectral range
- Proprietary Triplet spectrograph provides exceptional peak shape and maintains focus at all wavelengths
- Software controlled switching between confocal and high-energy collection modes
- Proprietary algorithm for automated cosmic ray rejection and high-quality laser line filters ensure artifact-free spectra
- Lasers depolarized to avoid confusing sample orientation effects
- Laser Power Regulator provides active monitoring of laser power and ensures reproducible laser excitation power over the lifetime of lasers and even after replacing lasers
- Optimized gratings for each excitation laser avoid performance sacrifices of systems that share gratings for multiple excitation lasers
- Proprietary autoalignment ensures system can be maintained in like-new condition
- Proprietary Smart-backgrounds automatically remove CCD dark energy profile
