visible radiation
Any optical radiation capable of causing a visual sensation directly.
NOTE There are no precise limits for the spectral range of visible radiation since they depend upon the amount of radiant power reaching the retina and the responsivity of the observer. The lower limit is generally taken between 360 nm and 400 nm and the upper limit between 760 nm and 830 nm. (CIE S 017/E:2011 ILV)
