Photometry is the science of the measurement of light, in terms of its perceived brightness to the human eye. It is distinct from radiometry, which is the science of measurement of radiant energy (including light) in terms of absolute power. In modern photometry, the radiant power at each wavelength is … See more The human eye is not equally sensitive to all wavelengths of visible light. Photometry attempts to account for this by weighting the measured power at each wavelength with a factor that represents how sensitive the eye is at that … See more Photometric measurement is based on photodetectors, devices (of several types) that produce an electric signal when exposed to light. … See more • List of light sources • Photometria • Photometry (astronomy) See more • Photometry (nist.gov) (archived) • Radiometry and photometry FAQ Professor Jim Palmer's Radiometry FAQ page (University of Arizona) (archived) See more Measurement of the effects of electromagnetic radiation became a field of study as early as the end of 18th century.
