FORAM

A RANGE OF RAMAN SPECTROMETERS FOR THE EXAMINATION OF QUESTIONED DOCUMENTS
 
Raman spectra exhibit numerous features that are specific to molecular structure and provide valuable "signatures" for comparing and differentiating materials, making it an ideal technique for examining ink and other materials attached to documents.
 
    Raman spectrum in under 1 minute
    Video imaging with XY translation stage
    Choice of two laser wavelengths
 
Foram is available with a choice of two laser wavelengths 785 nm, and 685 nm. The 785nm infrared laser is very able in suppressing fluorescence. The 685n m red laser is highly stable.
 
Instruments have an integral video microscope to assist sample selection, a large XYZ translation stage and dedicated software for analysis and database comparison.
