Photometry - an overview | ScienceDirect Topics
Photometry is a system of language, mathematical formulations, and instrumental methodologies used to describe and measure the propagation of light through space and materials . In consequence, the radiation so studied is confined to the visible (VIS) portion of the spectrum. Only light is visible radiation.
