Astrophotometry (from astro…, from Greek fotos “light” and…. metry “measure” ) A section of applied astrophysics dealing with the measurement of light fluxes of celestial bodies using optical detectors. To study the energy distribution in the difference of the incident beam, luminous flux measurements are used in several specific color ranges. Astrophotometry has recently been replaced by spectrometry.
