Zusammenfassung:FIELD: optical instrumentation engineering; optical instruments in which for selection of radiation of required wave length multiple action is used on the flux of radiation of dispersing element. SUBSTANCE: method includes multiple direction of radiation by means of multiple-pass reflecting system having reflectors with curved reflecting surface for at least one dispersing element, and at least for one compensating element straightening the curvature of image of spectral line and possessing angular dispersion which is lower than that of dispersing element. EFFECT: higher efficiency. 2 dwgi
