mini-PL/Raman Spectrometer

Fully Integrated with Excitation Energy up to 5.0 eV

The availability of the patented technology of deep UV (DUV) laser has led to the development of this compact, cost-effective DUV PL/Raman spectrometer. DUV laser Raman not only provides resonance enhancement of Raman scattering but also adds specificity and enhanced characterization of materials. In addition, because fluorescence resulting from deep UV excitation occurs in the 280nm to 370nm wavelength range, deep UV laser excitation provides the complete separation of Raman and fluorescence emission bands and results in high SNR and low detection limits. DUV Raman is a promising tool, particularly for analysis of biomolecular groups with complicated structures.
