Изобретение относитс  к области кинофототехники .The invention relates to the field of cinema and photo.

Известны менисковые телеобъективы, содержащие зеркально-менисковую систему и ахроматическую склеенную линзу, установленную между вторичным зеркалом и фокусо.м системы.Known meniscus telephoto lenses containing a mirror-meniscus system and an achromatic glued lens mounted between the secondary mirror and the focal point of the system.

Дл  увеличени  угла пол  зрени , фокусного рассто ни  объектива и укорочени  длины системы в предлагаемом телеобъективе склеенна  линза выполнена отрицательной.In order to increase the field of view, the focal length of the lens and shorten the length of the system in the proposed telephoto lens, the glued lens is made negative.

На чертеже представлена принципиальна  оптическа  система описываемого телеобъектива , состо щего из мениска /, обращенного вогнутостью к предмету, первичного сферического вогнутого зеркала 3, вторичного выпуклого сферического зеркала 3, жестко св занного с мениском /. Компенсатор, выполнен в виде ахроматической отрицательной линзы, склеенной из дво ковогнутой 4 и дво ковыпуклой 5 линз, и установлен в сход щемс  пучке позади зеркала 3 перед фокальной плоскостью 6 всего объектива.The drawing shows the principal optical system of the described telephoto lens, consisting of a meniscus / facing the concavity to the object, a primary spherical concave mirror 3, a secondary convex spherical mirror 3 rigidly connected with the meniscus /. A compensator, made in the form of an achromatic negative lens, glued together from bifurcated 4 and bifold convex 5 lenses, and installed in a converging beam behind mirror 3 in front of the focal plane 6 of the entire lens.

Предмет изобретени Subject invention

Менисковый телеобъектив, состо щий из зеркально-менисковой системы и ахроматической склеенной линзы, установленной между вторичным зеркалом и фокусом системы, отличающийс  тем, что, с целью увеличени  угла нол  зрени , фокусного рассто ни  и укорочени  длины системы, линза в нем выполнена отрицательной.A meniscus telephoto lens consisting of a mirror-meniscus system and an achromatic glued lens installed between the secondary mirror and the system focus, characterized in that the lens is made negative in order to increase the angle of sight, the focal length and the system.
