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. The basic principle is that each compound absorbs or transmits light over a certain range of wavelength.

The spectrophotometer is an instrument which measures an amount of light that a sample absorbs. The spectrophotometer works by passing a light beam through a sample to measure the light intensity of a sample. These instruments are used in the process of measuring color and used for monitoring color accuracy throughout production. They are primarily used by researchers and manufacturers everywhere. The major Spectrophotometer Applications are limitless as they are used in practically every industrial and commercial field, however it finds its major applications in liquids, plastics, paper, metals and fabrics. This helps in ensuring that the color chosen remains consistent from its original conception to the final, finished product.
