Abstract
Изобретение относитс к оптическому приборостроению, в частности к проекционным оптическим системам. Цель изобретени - повышение качества изображени . Объектив состоит из двух симметричных групп линз, кажда из которых содержит по шесть линзовых компонентов 1-6, разделенных диафрагмой 7. Компонент 1 выполнен в виде толстого отрицательного мениска. Положительный компонент 2 выполнен из плосковогнутой линзы 8, склеенной с дво ковыпуклой линзой 9. Положительный мениск 3 склеен из дво ковогнутой 10 и дво ковыпуклой 11 линз. Склееный компонент 4 состоит из дво ковыпуклой линзы 12 и плосковогнутой линзы 13. Отрицательный компонент 5 представл ет собой склейку из двух отрицательных менисков 14 и 15. Увеличение объектива-1х, числова апертура-03, линейное поле-4,2 мм, фокусное рассто ние одной линзовой группы-29,5 мм. 3 ил.This invention relates to optical instrument making, in particular to projection optical systems. The purpose of the invention is to improve the image quality. The lens consists of two symmetric groups of lenses, each of which contains six lens components 1-6, separated by a diaphragm 7. Component 1 is made in the form of a thick negative meniscus. The positive component 2 is made of a flat-concave lens 8, glued together with a double convex lens 9. The positive meniscus 3 is glued together from a double convex 10 and two convex 11 lenses. Bonded Component 4 consists of a biconvex lens 12 and the plano-concave lens 13. The negative component 5 is a gluing of the two negative menisci 14 and 15. The increase in x-1 lens, the numerical aperture-03, linear field-4.2 mm, the focal distance per lens group is 29.5 mm. 3 il.
