Principle of Materials Spectrometer
Spectrophotometry is a method to measure how much a chemical substance absorbs light by measuring the intensity of light as a beam of light passes through sample solution. When light passes through a sample, the molecules in the sample absorb some of it, and the rest passes through.

What does a spectrometer look like
A spectroscopic instrument, or spectrometer, generally consists of entrance slit, collimator, a dispersive element such as a grating or prism, focusing optics, and a detector. A spectrometer (/ spɛkˈtrɒmɪtər /) is a scientific instrument used to separate and measure spectral components of a physical phenomenon. Strictly speaking, a spectrometer is any instrument used to view and analyze a range (or a spectrum) of a given characteristic for a substance (for example, a range of mass-to-charge values as in mass spectrometry), or a range of wavelengths as in absorption spectrometry like nuclear magnetic. Optical spectroscopy is a technique that is used to measure light intensity in the ultraviolet (UV), visible (VIS), near-infrared (NIR), and infrared (IR) range of the electromagnetic spectrum.
