Description
силы, по модулю равной оптической силе первого компонента, наружные радиусы которого обращены вогнутостью к выходному зрачку .forces equal in magnitude to the optical power of the first component, the outer radii of which are turned by the concavity towards the exit pupil.
- В предлагаемом окул ре первый и второй компоненты обладают значительной положительной кривизной изображени , а соотношение их оптических сил, равное 1 : 0,75, позвол ет получить требуемое значение астигматизма; третий компонент обеспечивает телецентрический ход главного луча. Введение хроматических радиусов в три компонента позвол ет добитьс требуемой коррекции хроматических осевых и внеосевых аберраций при использовании всего двух сортов стекол, отличающихс по Пд на 1 10.- In the proposed eyepiece, the first and second components have a significant positive curvature of the image, and the ratio of their optical forces, equal to 1: 0.75, allows to obtain the desired value of astigmatism; the third component provides the telecentric motion of the main beam. The introduction of chromatic radii into three components allows one to achieve the required correction of chromatic axial and off-axis aberrations with the use of only two types of glasses differing in PD by 1-10.
Применение всего двух сортов стекол снижает стоимость окул ра, а равенство оптических сил первого и третьего компонентов облегчает их контроль в процессе сборки и юстировки, окул р имеет вынос выходного зрачка, равный 15 мм, чем обеспечиваютс оптимальные услови работы.The use of only two types of glass reduces the cost of the eyepiece, and the equality of the optical powers of the first and third components facilitates their control during the assembly and alignment process, the eyepiece has an exit pupil of 15 mm, which ensures optimal working conditions.
