(54) ОКУЛЯР(54) OCULAR

1one

I Изобретение может быть использовано 1 в различных телескопических системах, а также в микроскопах.I The invention can be used 1 in various telescopic systems, as well as in microscopes.

Из основного авт. св. № 2368ОО известен окул р, содержащий два положительных , одинаксаых и симметрично расположенных компонента, склеенных из двух линз с разностью показателей преломлени , не превышающей О,Об, и разностью коэффициенте средней дисперсии, превыщающей 15.From the main auth. St. No. 2368OO, an ocular is known, containing two positive, identically and symmetrically located components glued together from two lenses with a difference in refractive indices not exceeding O, O, and a difference in the coefficient of average dispersion exceeding 15.

Цель изобретени  - увеличение пол  зрени  и уменьшение дисторсии.The purpose of the invention is to increase the field of vision and reduce distortion.

Дл  этого в предлагаемом устройстве I позади симметричных компонентов размешена одиночна  положительна  линза.For this, in the proposed device I, a single positive lens is placed behind the symmetrical components.

На чертеже изображена оптическа  схе-j ма предлагаемого окул ра.IThe drawing shows the optical scheme of the proposed ocul pa. I

Окул р состоит из п ти линз 1-5, образующих три компонента 6, 7 и 8. Компоненты 6 н 7 - положительные, двухлинзсшые , склеенные, симметрично расположенные . Компонент 8 - положительна , одиночна  выпукло-вогнута  линза.The ocular consists of five lenses 1–5, which form three components 6, 7, and 8. Components 6 and 7 are positive, two-fold, glued, symmetrically located. Component 8 is positive, a single convex-concave lens.
