Schedule
Monday to Friday, from 10 a.m. to 2 p.m. and from 4 p.m. to 6 p.m.
  • Operational equipment
Microscope for Raman imaging.
    • Microscope with 10x, 20x, 50xLD, 50x and 100x lenses.
    •  Microscope with 2 diffraction grids for VIS and 2 diffraction grids for NIR.
    •  White light source with Köhler illumination.
    •  Confocal Raman image acquisition in XY.
    •  3D Raman microscopy.
    •  In depth Raman profiling (XZ and YZ plane imaging).
    •  3 lasers (488, 532 and 785 nm) with software-controlled power.
    •  2 tables (one motorised of 50x50 mm²) to measure Raman images of large areas and a piezo-electric table of 200x200x20 microns with a precision better than 2 nm in the x and y direction, and 0.2 nm in the z direction.
    • 2 back-illuminated Peltier-cooled CCD detectors with a quantum efficiency of more than 90% optimised for VIS and NIR.
    • 2 spectrometers with glasses.
    • The microscope is designed in a modular way, allowing the system to be easily extended to other techniques such as AFM, SNOM, etc.
    • Dynamic autofocus following the topography of the sample in real time True Surface.
    • WITec Project FIVE software that can be installed on any computer, with statistical tools (PCA, Cluster-Analysis), 2D and 3D Raman imaging, multiple algorithms for baseline subtraction, data export in ASCII, JCamp, SPC and Matlab.

  • IR-Raman unit
