HORIBA Jobin Yvon LabRAM HR Raman system


The LabRAM HR systems provide high spectroscopic resolution and a unique wavelength range capability that offers both great flexibility and high performance. They are widely used for standard Raman analysis, photoluminescence (PL), tip enhanced Raman scattering (TERS) and other hybrid methods.


High spectral resolutionThe unique high resolution mode is ideal for subtle band analysis such as that for phase (crystalline/amorphous), of proteins, weak bonding forces (such as hydrogen bonding) and semiconductor stress measurements – in fact most applications where it is important for the precise characterization of position or shape of the Raman spectral features. Band analysis with a resolution in the order of 0.3 cm-1 to 1 cm-1 is particularly suited to the high resolution mode. Its dual capabilities also enable more routine low/medium resolution Raman analysis and even broader band laser induced micro-fluorescence or luminescence to be conducted on the same bench-top instrument.

True confocal performance
The LabRAM HR has a true confocal pinhole with user controlled variable aperture. Unlike pseudo-confocal configurations (e.g., slit-binning methods) the confocal pinhole fully matches the laser spot and provides the highest spatial resolution with maximum signal throughput.

UV, visible and NIR capability
The LabRAM HR can be configured with the unique Dual Path Optics to allow UV-visible-NIR sensitivity without compromise. Unlike achromat (lens) based systems the Dual Path Optics offers fast, simple switching between UV and VIS/NIR regions. No adjustment or alignment is required.

Integrated upright, inverted and free space microscopes
Different applications can be best served with different microscopes – for this reason, the LabRAM HR can be configured with standard upright, inverted or free space microscopes.

  • The upright microscope is the standard option for materials analysis, and widely used for Raman analysis in many varied fields.
  • The inverted microscope is ideally suited for life science research, where tissue and live cells are frequently analysed within culture media.
  • The free space microscope provides a unique level of access to samples. The bottom frame is removable so that it offers a large free space beneath the microscope objective turret. Large cryostats, (e.g., liquid Helium cooled), sample environment equipment (diamond anvil cells) and similar devices can be accommodated with this microscope.
  • Dual microscope options are also available (for example, upright + inverted) – these allow the benefits of different configurations to be available on a single Raman instrument.

Fast Raman imaging
With the SWIFT™ and DuoScan™ fast Raman imaging technologies the LabRAM HR allows the collection of large area Raman images in the matter of seconds/minutes. The unique combination of innovative optics, detectors and software combine to provide true confocal Raman imaging with an unmatched speed of data acquisition.
