The paper is devoted to questions on optimization of comlex multi-band joint spectral measurements of environments objects. It is shown that results of joint multi-spectral measurements could be assessed by new indicator of authenticity expressed by signal-noise ratio at the output of spectral channels of multispectral measuring instrument.

Summing of such indicator on all spectral channels and substitute of researched object by model of ideal black body characterized by Plunk function make it possible to derive the formulae of optimal interrelation between mean quadratic deviation  of noises and model function. On the basis of said optimum interrelation function the new optimum interrelation function  concerning  dependence of mean quadratic deviation of noises on wavelength and absolute temperature is derived. It is shown that in optimum regime, upon some value of wavelength the mean quadratic deviation can reach the maximum amount i.e.  the authenticity of measuring results in this case would be minimum.
