FIELD: optical engineering. SUBSTANCE: optoelectronic camera has optical system, set of light-sensitive elements 3, type CCD, positioned in focus of the above-indicated optical system, transparent protective window manufactured for example of glass and placed in front of sensitive surface 4 of light-sensitive elements 3. It also includes dispersing device which provides for spectral analysis of scene observed by given optoelectronic camera. In this case, sensitive surface 4 of set of light sensitive elements 3 facing the protective window has single- or multi-layer coating made of antireflection material 9 thickness which varies continuously as function of wave length of light received by the above-indicated sensitive surface in parallel to diffusion axis of spectral diffuser, A. EFFECT: more efficient construction. 5 cl, 6 dwg
