Description

Предлагаемое изобретение имеет целью получение отклонени  оптической оси фотообъектива (например, аэросъемочного ) без внесени  каких-либо искажений в изображение, даваемое объективом, и с сохранением возможно малых габаритных размеров.The present invention aims to obtain a deviation of the optical axis of a photographic lens (for example, an aerial survey) without introducing any distortions into the image produced by the lens, while maintaining the smallest possible overall dimensions.

Изображенна  на чертеже составна  призма состоит из двух пар. призм /, /// и //, /V. Из них две полупенталризмы, / и //, имеют соответственно равные углы а, 3, у между своими гран ми, причем угол р между отражающими гран ми должен быть равен половине общего угла отклонени , даваемого всей системой . Отражающие грани /-2 и 3-5 призм посеребрены грани же 3-4 и 6-7 работают на полном внутреннем отражении.The composite prism shown in the drawing consists of two pairs. prisms /, /// and //, / v. Of these, two semipentalisms, / and //, have respectively equal angles a, 3, y between their faces, with the angle p between the reflecting faces being equal to half the total angle of deflection given by the entire system. Reflecting edges / -2 and 3-5 prisms are silvered; the edges 3-4 and 6-7 work on complete internal reflection.

Призмы /// и IV представл ют собой накладки, имеющие равные углы р, которые дают совместное развертывание пар призм /, /// и //,/Кв плоско-параллельные пластинки.The prisms /// and IV are patches having equal angles ρ, which give the joint deployment of a pair of prisms /, /// and //, / K, plane-parallel plates.

Призмы /, /// и //, IV не склеены и имеют между собой прокладки из станиол  (дл  получени   влени  полного внутреннего отражени  на гран х 3-4 и 6-7 призм / и //), и должны быть изготовлены из одного сорта стекла.The prisms /, /// and //, IV are not glued together and have stanoliol spacers between them (to obtain a complete internal reflection on the edges x 3-4 and 6-7 prisms / and //), and must be made of one varieties of glass.

Описанное сочетание двух систем призм создает сильное уменьшение габаритов .The combination of two prism systems described creates a dramatic reduction in size.

Предмет- изобретени .The subject invention.

Составна  призма дл  отклонени  пучка параллельных лучей, отличающа с  тем, что она состоит из двух пар /, /// и //, IV трехгранных призм, входные и выходные грани которых нормальны к вход щему и выход щему пучку лучей, причем углы между отражающими гран ми 7, 2-3, 4 v 3, 5-6, 7 призм I и II равны половине общего угла отклонени , даваемого всей системой .Composite prism for deflecting a beam of parallel rays, characterized in that it consists of two pairs of /, /// and //, IV trihedral prisms, whose entrance and exit faces are normal to the incoming and outgoing beam, and the angles between facets 7, 2-3, 4 v 3, 5-6, 7 of prisms I and II are equal to half the total angle of deflection given by the whole system.
