Irradiance of the surface per device frequency or wavelength. The conditions spectral flux density or even more confusingly "spectral intensity" also are employed. Non-SI units of spectral irradiance include things like Jansky = 10 W⋅m⋅Hz and photo voltaic flux unit (1SFU = 10 W⋅m⋅Hz). The Dean of Methods Hub https://jakez864sbj1.magicianwiki.com/user
