In astronomy, the term spectrophotometry refers to the measurement of the spectrum of a celestial object in which the flux scale of the spectrum is calibrated as a function of wavelength, usually by comparison with an observation of a spectrophotometric standard star, and corrected for the absorption of light by the Earth's atmosphere.
A spectrophotometer is one of the scientific instruments commonly found in many research and industrial laboratories. Spectrophotometers are used for research in physics, molecular biology, chemistry, and biochemistry labs.hey measure the absorbance, which is known as the optical density (OD), on a spectrophotometer. One can tell from the OD whether the bacteria are actively dividing or whether they are starting to die.
