Note
Characteristics of Relative Visible-spectrum
Response
The visible spectrum of light to which human beings are considered
sensitive has an extremely narrow range: 360 to 830 nm. Within this range,
sensitivity differs greatly depending on the wavelength. This phenomenon
is called standard spectrum luminous efficiency, indicated by V (
λ
). An
illuminance meter is used to measure the luminous intensity, and the
characteristics of relative visible-spectrum response plays an important role
in illuminance measurement. This meter, rather than the human eye, brings
these characteristics to the same degree of brightness as V (
λ
).
