Paint, fiber and dye which play a critcal role in proving the relationship between a suspect and a victim or a crime scene, are one of the most frequently encountered trace evidences at a forensic laboratory, however, in usual, because of infinitesimally small sizes of forensic samples, investigation of the spectroscopic characteristics of such samples is becomming more and more prevalent in forensic science as a non-destructive method. In this study, transmittance/reflectance profiles at ultraviolet-visible region (240-780nm), were investigated by UV/visible microspectro- photometer and used to analyze the spectral characteristics of different types of 14 microfibers, 12 inks of four colors and 44 automotive paints of two colors. Good results for discrimination were given from spectra of these samples due to the characteristic bands in uv/vis region, respectively.
