Focas Research Institute RAMAN Request Form

‌Overview:

The Horiba Jobin Yvon LabRAM HR system provides ultra high spectroscopic resolution and a unique wavelength range capability that provides both great flexibility and high performance.
It is a an integrated, simple to use, and high stability bench-top instrument designed to undertake reproducible Raman measurements at high, medium or even low spectral resolution. The high resolution mode is uniquely ideal for subtle band analysis such as that for phase (crystalline/amorphous), of proteins, hydrogen and weak bonding forces 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 in the order of 0.3 cm-1 to 1 cm-1 is particularly suited to the HR mode. Its dual capabilities also enable more routine Raman analysis and even broader band laser induced micro-fluorescence or luminescence to be conducted all upon the same bench-top instrument.
