Description
Предметом изобретени вл етс установка дл исследовани нарушений гомоцентричности световых пучков.The subject of the invention is an apparatus for investigating violations of the homocentricity of light beams.
Известные того же назначени установки требуют дл определени кривых аберраций производства многих измерений, св занных с изменением положени тех или иных .деталей в процессе измерени .Installations of the same purpose require, for defining aberration curves, the production of many measurements associated with a change in the position of one or another of the parts during the measurement process.
В предлагаемой з становке этот недостаток устранен тем, что, с целью наблюдени в поле зрени непосредственно свет щихс кривых .аберраций, установка снабжена .двум скрещенными спектральными .призмами, Поставленными перед и Сзади двух коллиматоров, в фокаль ,ной плоскости одного из которых и между ними установлены перпендикул рно одна к другой две щели.In the proposed installation, this disadvantage is eliminated by the fact that, for the purpose of observing directly luminous curves of obstructions in the field of view, the installation is equipped with two crossed spectral prisms, placed in front of and behind two collimators, in the focal plane of one of which and between they have two slits perpendicular to each other.
На фиг. 1 показана установка в разрезе; на фиг. 2 - процесс об ..разовани кривой аберраций, наблюдаемой в окул р установки.FIG. 1 shows a sectional installation; in fig. 2 - the process of formation of the curve of aberrations observed in the eye of the installation.
Лучи света от источника / (фиг. 1) проход т через щель 2 монохроматор 3 и образуют в фокальной плоскости 4 коллиматора 6 сплощной спектр. Выйд из колли .матора 5 и пройд щель 5, лучи параллельным пучком направл ютс во встречный коллиматор 7 и через щель 8, призму 9 и зрительную трубку W небольшого увеличени попадают в глаз наблюдател .Rays of light from the source / (Fig. 1) pass through the slit 2 of the monochromator 3 and in the focal plane 4 of the collimator 6 form a flat spectrum. The exit of the collie 5 of the matrix and the passage 5 of the gap 5, the rays of the parallel beam are directed into the counter collimator 7 and through the slot 8, the prism 9 and the optic tube W of a small magnification into the eye of the observer.
Исследуема оптическа деталь (или система) 11 помещаетс в параллельном пучке лучей и в промежутке между двум коллиматорами 5 и 7. Щели 2 и 8 параллельны одна другой, а щель 6, лежаща в плоскости чертежа длиной, равной диаметру коллиматора (линзы) 5, перпендикул рна им. Призма 9 установлена в приборе перпендикул рно призме монохроматора 3.The optical part (or system) 11 under investigation is placed in a parallel beam of rays and in the gap between two collimators 5 and 7. Slots 2 and 8 are parallel to each other, and the slot 6 lying in the drawing plane with a length equal to the diameter of the collimator (lens) 5 is perpendicular rna them. The prism 9 is installed in the device perpendicular to the prism of the monochromator 3.
При удалении из прибора исследуемого объектива и призмы 9 наблюдатель видит в трубку 10 щель 6, равномерно залитую светом, цвет которого соответствует цвету участка спектра, наход щегос на оптической оси установки (место пересечени пунктирных линий на чертеже ). Если между коллиматорами 5 и 7 поместить оптическ)ю деталь // с переменными параметрами в различных зонах А, Б, В, Г и Д, то в глаз наблюдател попадет уже с плоскости 4 значительный участокWhen a lens and a prism 9 are removed from the instrument, the observer sees into the tube 10 a slit 6 uniformly flooded with light, the color of which corresponds to the color of the part of the spectrum located on the optical axis of the installation (the intersection of the dotted lines in the drawing). If between the collimators 5 and 7 we place an optical detail // with variable parameters in different zones A, B, C, D and D, then a significant segment will fall into the eye of the observer from plane 4
