Calculating energy from flux and max wavelength

[ShalinNayak]

hey I am 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$^{4}$.
