Photometry: The Answer to How Light Is Perceived - Photonics

WebDesign Master Photometrics is an add-in for AutoCAD and BricsCAD that calculates outdoor illuminance levels. It allows civil engineers and landscape architects to perform their own outdoor site lighting calculations. Illuminance Levels: Calculate point-by-point illuminance levels on your site plan and have them displayed directly on your drawing. 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.
