Built around a Leica DMI6000 automated epifluorescence microscope, the Renishaw confocal Raman microscope allows spatially resolved spectroscopy to be carried out in a confocal manner at high speed. The system can acquire Raman or PL spectra using any one of 3 solid state excitation sources (532nm, 638nm, 785nm) and a deep-depletion silicon CCD detector which has sensitivity from approximately 400-1000nm. The inverted microscope base allows for imaging of live cells or animals in typical environmental chambers which fit the Prior H117 mapping stage. All optical components (holographic notch filters, gratings, beam expansion/linefocus lenses, polarizers) are motorized and encoded, allowing for automated collection of multiple experimental conditions serially.
