The effective emissivity of nonisothermal diffuse cavity radiators is numerically computed as a function of the bandwidth of the radiation. The deviation of the integrated cavity emissivity due to nonisothermality is small for small distances of the detector from the cavity, independent of the bandwidth. Consideration is given to the observed wavelength characteristic of the effective emissivity.
