LabRam HR Evolution Raman Spectrometer is equipped with the 266 nm (mtb, CryLas, FQCW266 with a nominal 100 mW out-put power) excitation diode laser. In addition, the instrument is equipped with a Syncerity CCD detector and is coupled to a BXFM microscope (Olympus, Japan), implementing a Z motor and XY SCANplus 75x50 2 mm motorized microscope stage control toolbar (Märzhäuser Wetzlar, Germany) and equipped with a micro-camera for searching the points of interest and performing Raman images. 5x MPlan N (0.10 NA, Olympus), 10x MPlan N (0.25 NA, Olympus) and 100x MPlan N (0.90 NA, Olympus) objectives are used for visualization and focusing, whereas the 74x UVI (0.66 NA, Horiba) objective is used for ultraviolet measurements. The nominal power of the source can be modulated between 0.01-100%. The ultraviolet laser is daily calibrated setting the 1332.5 cm-1 diamond line. The Raman data obtained with the LabRam HR Evolution Raman spectrometer is acquired with the LabSpec 6.0 software (Horiba, Japan).
