Abstract

Изобретение относится к оптико-электронному приборостроению, а именно к объективам, и может быть использовано в качестве объектива прибора ночного видения (ПНВ). Объектив содержит последовательно расположенные по ходу лучей двояковыпуклую линзу, мениск, положительный мениск, обращенный выпуклой поверхностью к пространству предметов, и одиночную линзу, отличающийся тем, что мениск выполнен склеенным из двояковыпуклой и двояковогнутой линз, отстоящим от двояковыпуклой линзы на расстоянии не менее 0,25 фокусного расстояния объектива, а между положительным мениском и одиночной линзой введен отрицательный мениск, обращенный выпуклой поверхностью к пространству предметов, при этом одиночная линза имеет двояковыпуклую форму. Предложенная конструкция объектива позволяет улучшить качество изображения за счет увеличения полихроматических частотно-контрастных характеристик объектива по полю зрения.The invention relates to opto-electronic instrumentation, namely, lenses, and can be used as a lens night vision device (NVD). The lens contains a biconvex lens sequentially arranged along the rays, a meniscus, a positive meniscus facing a convex surface to the space of objects, and a single lens, characterized in that the meniscus is made glued together from a biconvex and biconcave lens that is separated from the biconvex lens at a distance of not less than 0.25 the focal length of the lens, and between the positive meniscus and a single lens, a negative meniscus is introduced, facing a convex surface to the space of objects, with a single lens and has biconvex shape. The proposed design of the lens can improve image quality by increasing the polychromatic frequency-contrast characteristics of the lens in the field of view.
