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.
Colorimetry is the analysis of chemical samples to collect information about their concentration.It involves passing light through a sample and measuring how much is absorbed by the solution, using equipment like a spectrophotometer to measure as precisely as possible. spectrophotometer may be used during colorimetry. The therm colorimetry may be used to describe the study of how people perceive color and distinguish between colors. Colorimetry can be used to help people with colorblindness.
