PHOTOGRAPHIC LENS Russian patent published in 2002 - IPC

FIELD: formation of pictures of objects on ground surface through real atmosphere. SUBSTANCE: proposed photographic lens is made up of two components. Positive component comprises individual lenses positioned in sequence, first of them being positive meniscus facing picture with concavity, second lens being positive meniscus facing picture with concavity, third lens being negative meniscus facing picture with concavity and fourth lens being biconvex lens. Second component is negative component that includes four individual lenses, first lens being biconvex lens, second lens being biconcave lens, third lens being biconvex lens and fourth lens being positive meniscus facing picture with concavity. Given photographic lens provides for diffraction quality of picture in spectral range from 500 to 900 nm securing identical images in three regions of spectrum: 540-590 nm, 630-680 nm, 790- 900 nm. EFFECT: raised quality of pictures. 2 cl, 1 dwg, 1 tbl
