1.1 This guide is intended to assist forensic examiners who conduct ultraviolet (UV), visible, near infrared (NIR), or fluorescence emission spectral analyses on single fibers. This guide is to be used as a part of a broader analytical scheme. 1.2 This guide deals primarily with color measurements within the visible spectral range but will also include some details concerning measurements in the UV and NIR spectral ranges. The particular method(s) employed by each analyst depends upon available equipment, examiner training, sample suitability, and sample size. 1.3 This guide provides basic recommendations and information about microspectrophotometers.
MSP; spectral comparison
Provide standard guidance in conducting microspectrophotometry (MSP) in the analysis of forensic fibers.
