Hello. I am interested to read more about the potential sources of variation in measurement with an NIR Spectrometer. Specifically the effect of environmental conditions and of nearby system interactions, such as ambient radiation, ambient temperature, temperature of instrument or workpiece, contamination on the surface of the workpiece, complexity of workpiece composition, etc. Could you help me with some reading suggestions? Thanks! Odysseas
