From Light to Data: The Technology of Colorimetry and Spectrophotometry

What is colorimetry: Colorimetry is simply the measurement of color. Colorimetry is the determination of the concentration of a substance by measuring the relative absorption of light relative to a known concentration of the substance. In visual colorimetry, natural or artificial white light is usually used as the light source, and measurements are usually made using a simple instrument called a c...
