Examples from texts

A system for the precise setting of the initial lens turning angles is necessary for controlling the astigmatism corrector.
Для управления астигмокорректором необходима система точного выставления начального угла поворота линз.
Excess of energy must be absorbed by a filter 6 before a radiation enters in the channels, placed more close to a longitudinal axes of a half lens.
Для более близких к продольной оси полулинзы каналов избыток энергии должен быть поглощен фильтром 6 еще до входа излучения в эти каналы.
In contrast to the angular resolution, the spatial resolution Ax at the image plane, depends according to Eq. only on the relation of the radius of the lens aperture to the distance / of the image of the object from the principal point.
В отличие от углового разрешения, пространственное разрешение Ах на плоскости изображения зависит, согласно уравнению, только от отношения радиуса апертуры линзы к расстоянию/от изображения объекта до главной точки.

The aperture equals the sine of the maximum angle defined by the light emerging from the object that is still incident upon the lens.
Она равна синусу максимального угла, который образует идущий от объекта луч, еще попадающий в объектив.
It can be seen from an intensity profile (see FIGS. 4 and 7) along segments A and B shown in FIGS. 6 and 9 that the microscope lens that was used in the experiment could not ensure the necessary resolution for obtaining a crisp image of Sets 1 and 2.
По распределению интенсивности (смотри фиг. 4 и 7), вдоль отрезков А и В показанных на фиг. 6 и 9 видно, что используемый в эксперименте объектив микроскопа не способен дать необходимое разрешение для четкого наблюдения групп 1 и 2.
If a radiation rotation angle is equal to 30° relevant to a respective capture angle 60°, taking place in peripheral channels of a lens, only about 5% of energy is transferred to a channel output.
При угле поворота излучения 30°, соответствующем углу захвата 60°, которое имеет место в периферийных каналах линзы, только около 5% энергии передается на выход канала.
The lens raster is located in front of the projection lens of the stereoscopic lens assembly in the plane of the obj ects clearly represented on the stereoscreen.
Линзовый растр расположен перед проекционными объективами стереообъектива в плоскости резко изображаемого на стереоэкране пространства предметов
Additional effect— maximal simplicity of the stereolens design due to the lens elimination (causing optical distortions and glares).
Дополнительный результат - максимальная простота конструкции стереообъективов за счет исключения линз (со всеми оптическими искажениями и бликами в линзовых объективах).
But sometimes you need to shade the lens from the sun or hold a small item while you photograph it.
Но иногда необходимо прикрыть объектив от солнца или держать какой-либо предмет во время его съемки.

So, the studied system, including a tube of 30 kW power and a half lens with 60° capture angle, meets accepted requirements with safety from the point of view of energetics of lithographic process.
Таким образом рассмотренная система с трубкой мощностью 30 кВт и полулинзой, имеющей угол захвата 60° с запасом удовлетворяет принятым требованиям с точки зрения энергетики литографического процесса.
The prism (7b) travels to such a distance that the focal plane of the lens (7a) becomes accessible.
Призма 7b сдвигается на такое расстояние, что доступной становится фокальная плоскость линзы 7а.
L is a length of a half lens;
L - длина полулинзы;
You already know that a photograph obtained with the aid of a lens having a focal distance of 25-30 cm will appear in relief when viewed with one eye from the usual distance away.
После сказанного раньше понятно, что снимок, полученный при помощи объектива с 25 — 30-сантиметровым фокусным расстоянием, можно рассматривать (одним глазом) на обычном расстоянии — он покажется достаточно рельефным.

Besides, the influence of actual out- of-parallelism of emergent radiation of a half lens appears in this variant to a greater extent.
Кроме того, в этом варианте в большей степени проявляется влияние фактической непараллельности выходного излучения полулинзы.
