calculating energy from flux and max wavelength

[ShalinNayak]

hey im calculating energy of a blackbody emitter, and i have the flux (energy per unit area) and the peak wavelength emitted. how do i calculate total energy?

Since you have your peak wavelength, use Wein's Displacement Law to find the temperature of your black body emitter:

\lambda_{max} T = 2897.8 um-K

Then apply Stepan-Boltzmann Law to find total power:

E = \sigma T^{4}.
