      <abstract xml:lang="ru">
        <p>В последние годы для получения поляризованного света широко применяются дихроичные поляроиды. Достоинствами их является сравнительная дешевизна, малая толщина, большая линейная и угловая апертура. Основными же недостатками можно считать следующие. Пропускание селективно по спектру, в результате чего значительно искажается спектральное распределение энергии в исследуемом световом потоке. ...</p>

      <abstract xml:lang="en">
        <p>In recent years, dichroic polaroids have been widely used to produce polarized light. Their advantages are comparative cheapness, small thickness, and large linear and angular aperture. The main disadvantages are the following: transmission is selective across the spectrum, as a result of which the spectral distribution of energy in the light beam under study is significantly distorted. ...</p>
