Raman spectrometer (Operational)
Raman |
The RenishawinVia Raman system has three interchangeable holographic gratings and a silicon CCD detector (576 x 384-pixel, Peltier-cooled to -70°C) to provide high sensitivity. Samples are analysed on a specially adapted Research Grade free space microscope equipped with oculars, a colourvideo camera, objectives and a motorized sub-micron resolution XY- and Z-travelstage. The samples can be probed by a range of laser wavelengths for different capibilities/applications. The spectrometer and microscope are fully computer-controlled by Windows-compatible software which acquires the Raman data, captures the video images, and searches for the minerals and polymer database.
