FIELD: study of spectra of sources of optical radiation. SUBSTANCE: spectrum analyzer has family of optical fibers whose inputs are inputs of analyzer. Outputs of optical fibers are optically coupled via color division prism to inputs of photoelectron converters whose outputs are connected via commutator to input of analog-to-digital converter, output of the latter being connected to inputs of personal computer. Information outputs of personal computer are information outputs of analyzer. Controlling output of personal computer is connected to controlling input of commutator. Outputs of optical fibers are arranged in one line for change of angle of incidence and displacement along boundary of color division prism. EFFECT: enhanced precision and authenticity of measurement thanks to exclusion of possibility of superimposition of spectra of different points of light spot, simplified process of adjustment and re-adjustment of analyzer. 1 cl, 4 dwg
