Description
Изобретение ставит своей целью создание ортоскопически коррегированного широкоугольного светосильного анастигмата , пригодного дл аэрофотосъемки.The invention aims to create an orthoscopically corrected wide-angle aperture aperture suitable for aerial photography.
Предлагаемый объектив состоит из двух отрицательных линз / и ///, расположенных по обе стороны центральной положительной части /7 объектива и взаимно уравновешивающих друг друга в отношении исправлени дисторсии, комы и т. д., и центральной положительной части //, состо щей из двух половин , из которых кажда склеена из трех стекол: 1) плосковыпуклой линзы, близкой по размерам к полусфере, причем коэфициент преломлени ее ниже, чем третьей линзы; 2) тонкой линзы-прослойки, имеющей , радиусы кривизны обеих по1 . F 15fl, относительное отверстие 1The proposed lens consists of two negative lenses / and /// located on both sides of the central positive part / 7 of the lens and mutually counterbalancing each other in terms of correcting distortion, coma, etc., and the central positive part //, consisting of two halves, each of which is glued together from three glasses: 1) a convex lens, close in size to a hemisphere, with a refractive index lower than the third lens; 2) a thin interlayer lens having radii of curvature of both po1. F 15fl, relative aperture 1
верхностей концентрическими и коэфициент преломлени ниже, чем у плосковыпуклой линзы; 3) толстой линзы, точно так же имеющей радиусы кривизны обеих поверхностей концентрическими и обладающей коэфициентом преломлени , большим, чем у плоско-выпуклой линзы и тонкой концентрической линзы-прослойки . Сорта стекол линз обеих половин центральной части попарно одинаковы , за исключением сортов стекла плоско выпуклых линз, обладающих одинаковыми коэфициентами преломлени , но различными дисперси ми дл целей исправлени хроматизма увеличени .the surfaces are concentric and the refractive index is lower than that of a convex lens; 3) a thick lens, which similarly has radii of curvature of both surfaces, concentric and having a refractive index greater than that of a flat-convex lens and a thin concentric interlayer lens. The lens glass grades of the two halves of the central part are identical in pairs, except for the glass grades of flat convex lenses having the same refractive index, but different dispersions for the purpose of correcting the chromatism of magnification.
