Identification of Inorganic Filler Materials in Polymers
Combined investigations in the far- and mid-infrared region in a single scan can offer great value for the analysis of polymeric materials. With the use of optical components optimized for combined FIR-MIR spectroscopy, consisting of a wide range mid to far IR beamsplitter and detector, the investigation of both spectral regions in single step is possible.

SERS for Label-Free Biosensing
Surface enhanced Raman spectroscopy (SERS) has expanded the applications of Raman spectroscopy to include trace analysis of materials such as explosives residues, evidence at crime scenes, chemical warfare agents and pesticides. As a label-free technique, SERS is also well suited to biosensing, from blood glucose to diagnosis of diseases like cancer, Alzheimer's, and Parkinson's.

Two Raman Lasers Better Than One
Because of the resolution and improved Raman scattering efficiency, library matching using 785 nm excitation is preferred for low-fluorescence materials. However when fluorophores are present, significantly better Raman spectra can be obtained with longer-wavelength excitation.
