retinal thermal radiance

LR; Lr

effective radiance with the spectral radiance, Lλ, spectrally weighted with the retinal thermal hazard spectral weighting function, r(λ)

Note 1 to entry: The wavelength range for retinal thermal radiance is the retinal hazard spectral region.

Note 2 to entry: This definition is based on the assumption that an action spectrum is adopted for the effect considered, and that its maximum value is 1.

Note 3 to entry: It is essential to specify which action spectrum is used, as the unit is the same for any action spectrum.

Note 4 to entry: The retinal thermal radiance is expressed in watt per square metre per steradian (W⋅m−2·sr−1).

Note 5 to entry: This entry was numbered 17-1102 in CIE S 017:2011.
