LabRam HR Evolution Horiba Raman
Advanced confocal micro-Raman set up, with an excitation range from 325 nm to 785 nm. A temperature control unit and various polarization apparatus are available, enabling the performance of Raman measurements at a wide range of experimental conditions.
Lasers: 325 nm, 532 nm, 633 nm, 785 nm.
- Linear polarizers.
- Heating-cooling stage. Min. temperature: -196 ºC; Max. temperature: 600 ºC.
- Ultra Low frequency (ULF) module allows the sample characterization to be made at very low frequencies (for 532 nm laser, from 10 cm-1), as well as the measurement of anti-Stokes spectra.
Detectors and gratings: Cooled CCD detector, 1024 pixel size.
Raman mapping: Several options for Raman mapping, with sub-micrometer spatial resolution, and options of large mapping area using micro and macro-spots (up to 300 mm size)
Several methods for analyzing mapping data /multicomponent systems:
- Decomposition algorithms: Classical Least Squares (CLS), Principal Component Analysis (PCA) and Multivariate Curve Resolution (MCR).
- Clustering techniques (grouping of objects having similar spectral properties): Hierarchical Component Analysis (HCA) and Divisive Cluster Analysis (DCA).
- Particle Finder module (analysis of particulate materials): offers particles parameters such as location, size and shape followed by chemical characterization with Raman.
