Paper Abstract

Microspectrophotometers capable of obtaining absorption or reflectance spectra of samples down to 2 micrometers in size will be discussed. Variations of spectra obtained from fibers, paint chips, colored dots and inks are remarkably different for dyes and pigments which appear similar to visual examination. Without cumbersome sample preparation, microspectrophotometry is therefore a fast and ideal technique for matching unknowns to specific materials for forensic investigations and document verification.
