Description

Известные зрительные трубы различных оптических систем имеют, как правило, лиизэвые фскусирующие компоненты, обладающие следующими недостатками: перемещение фокусирующего компонента При наблюдении разноудаленных объектов вызывает больщую ощибку направлени  (пор дка нескольких секунд); зпачительные аберрации объектива.The known telescopes of various optical systems, as a rule, have liquefied fccus components, which have the following disadvantages: moving the focusing component When observing objects of different distances, causes a large error in direction (in the order of a few seconds); spectacular lens aberrations.

Предлагаемый объектив устран ет эти недостатки, дл  чего в нем в качестве фокусирующего компонента использована зеркально-призменна  система, примеиеиие которой уменьшает габариты зрительной трубы и обеспечивает получение изображени  более высокого качества.The proposed lens eliminates these disadvantages, for which it uses a mirror-prism system as a focusing component, the use of which reduces the size of the telescope and provides a higher quality image.

На чертеже представлено схематическое устройство зеркально-призмеиной системы, состо щее из объектива /, двух зеркал 2 и двух пентопризм 3, которые укреплены в специальной оправе 4. Перемещение оправы 4 с призмами 3 перпеидикул рно оптической оси иоззол ет фокусировать объектив на разноудаленные объекты.The drawing shows a schematic device of a mirror-prism system consisting of a lens /, two mirrors 2 and two pentoprisms 3, which are fixed in a special frame 4. Moving frame 4 with prisms 3 perpendicular to the optical axis and focus the lens on distant objects.

Предмет изобретени Subject invention

Объективе внутренней фокусировКой, отличающийс  тем, что, с целью получени  более высококачественного изображени  и сокращени  осевых габаритов, в нем применена в качестве фокусирующего компонента зеркально-призмепна  система, состо ща  из двух зеркал, расположенных под углом друг к другу на оси объектива, и двух пеитопризм , укрепленных в оправе, перемещение которой перпендикул рно оптической оси позвол ет производить иерефокусировку объектива.The lens has an internal focus, characterized in that, in order to obtain a higher quality image and reduce axial dimensions, the mirror-prisme system consisting of two mirrors at an angle to each other on the axis of the lens and two Peitoprisms fixed in a frame, the movement of which is perpendicular to the optical axis allows for lens and focus focusing.
