Concept: Photometry in the analyticaltechnique vocabulary

Concept URI	http://dd.eionet.europa.eu/vocabulary/aq/analyticaltechnique/photo
Preferred label	Photometry
Definition	Photometry is the science of the measurement of light, in terms of its perceived brightness to the human eye.[1] It is distinct from radiometry, which is the science of measurement of radiant energy (including light) in terms of absolute power; rather, in photometry, the radiant power at each wavelength is weighted by a luminosity function (a.k.a. visual sensitivity function) that models human brightness sensitivity.
