absorbed (spectral) radiant power density

Spectral radiant energy per time interval (spectral radiant power, $P λ$ ) absorbed by a system per volume, $V$ . SI unit is $W m −4$ ; common unit is $W cm −3 nm −1$ .

Note:

Mathematical expression: $P λ 0 1 − 10 − A λ V$ , where $A λ$ is the absorbance at wavelength $λ$ and superscript $0$ (zero) indicates incident radiant power.
