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 three laser wavelengths
 
Foram is available with a choice of three laser wavelengths 785nm, 685nm and 532nm. High levels of sensitivity can be achieved with the 532nm laser, while the 785nm infrared laser is better able to supress fluorescence. A highly stable 685nm red laser provides a third option.
 
Instruments have an integral video microscope to assist sample selection, a large XYZ translation stage and dedicated software for analysis and database comparison.
