Zusammenfassung:	FIELD: optical sights and telescopes operating in the visible range of radiation spectrum. ^ SUBSTANCE: the sight with an alternating magnification has a three-lens objective, sight reticule, field component, two-component panchromatic erecting system, range-finding reticule, collective lens and an ocular installed in succession in the direction of rays. The objective has cemented first two lenses-biconvex and negative ones, and the third lens-singular positive meniscus turned with the convexity to the object. The biconvex and singular lenses are made of the same material with dispersion factor nuD, which corresponds to condition 50
