retinal thermal radiance
effective radiance with the spectral radiance,
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.
