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