Liquid ID Spectrometer

Background

A spectrometer is an optical instrument used to measure the properties of light over a specific portion of the electromagnetic spectrum. Spectroscopic analysis is used to identify materials. All materials have a spectral signature. The spectral signature of some materials is within or near the visible light portion of the electromagnetic spectrum. By measuring the intensity of light at each wavelength a spectrometer can determine the spectral characteristics of a material under investigation.
