Horiba Labram HR Evolution Raman System

Main content start


Confocal Raman spectroscopy and imaging provides specific chemical information about your nano-materials, with sub-micron spatial resolution. The HORIBA Scientific LabRAM HR Evolution spectrometer, seamlessly integrated with AIST-NT’s SmartSPM Scanning Probe Microscope, offers the most versatile and reliable platform for both fast simultaneous co-localized Raman-AFM and TERS measurements. Tip-enhanced Raman Spectroscopy (TERS) provides the chemical specificity of Raman spectroscopy with imaging at spatial resolution typically down to 10nm. The system may also be used for Raman or AFM only measurements.

  • 4 laser sources: 405 nm, 532 nm, 633 nm, 785 nm
  • There are three grating options that you can use with the LabRam. By selecting either the 300 l/mm, 600 l/mm, or 1800 l/mm the user can optimize their signal intensity, measurement range, and spectral resolution for their experimental needs.
  • Automated mapping routines enable precise measurement of surface features. Rough surfaces can be maps using the Duoscan feature and SWIFT Mode minimizes data processing delays. 
  • Stokes or anti-stokes Raman scattering modes can be measured.
  • Custom software allows the user adjusting laser intensity, scan range, and a variety of other measurement and acquisition parameters to fine tune the measurement to the specific needs of their samples.

Please note that while the instrument is available for general use, the TERS technique is still under development.
