Measurer of the atmosphere’s spectral transparency

Optical-electronic measuring complex is described, intended for the operative measurement of atmosphere’s transparency in the wavelengths region of $0.35-1.03\mu m$ and of the meteorological optical range in the different climatically conditions from $0.1$ to $300 \ km$. The technique of realization of full-scale measurement of a parameter of atmospheric easing for seen beams (on $\lambda=0.55\mu m$) with sensitivity not worse $3.4\times10^{–5} km^{–1}\cdot mV^{–1}$ is stated.
