PVMS – Portable Video Micro Spectrometer
for VSC® Range
VSC80/PVMS
A plug-in accessory for VSC document examination workstations, the Portable Video Micro Spectrometer enables the forensic document examiner to identify differences in ink and paper formulations through non-destructive spectral analysis.
Adding further functionality to VSC workstations, this compact fibre-coupled spectrometer, with 3x zoom microscope, captures real-time absorption, reflectance, fluorescence and transmitted
spectra to be displayed on-screen in a simple graphical format.
An ideal technique for the discrimination of visually similar inks, including ball point and liquid ink pens, micro spectrometry has also been demonstrated to be an effective in the study of the sequence of intersecting lines (Biao Li, 2016)
