fotoptik (kal) aur skoptik^[1] (hara) lyoominॊsiti fnkshan. fotoptik mein CIE 1931 maanak^[2] (thos), Judd-Vos 1978 soodhaara data^[3] (daishd) aur sharp, stॊkmain, jaagla & jaagle 2005 data^[4] (dॊted). kshaitij aksh par tarangdairghya hai nm mein.

kaindila (IPA: /kanˈaadɛaalə/, /-ˈaadiːaalə/, prateek : cd) deept teevrata SI ikaai hai. yeh ek mool ikaai bhi hai.

${\displaystyle I_{V}={\frac {dF}{d\Omega }}}$

ya:

${\displaystyle I_{V}=K\int _{visible}^{\ }I(\lambda )V(\lambda )\,d\lambda }$
