Abstract
Изобретение относится к оптоэлектронной технике, в частности к оптическим системам коллиматорных прицелов, позволяющих точно наводить оружие на цель при стрельбе в различных условиях освещенности. Оптическая система коллиматорного прицела содержит мениск, обращенный выпуклостью к объекту прицеливания, одна из поверхностей которого отражает излучение прицельной марки. Между мениском и прицельной маркой, смещенной с оптической оси мениска, введена положительная линза, выполненная в виде линзового фрагмента и установленная от мениска на расстоянии d', удовлетворяющем условию 0,7d<d'<0,9d, где d - расстояние от мениска до прицельной марки, при этом положительная линза имеет фокусное расстояние f, удовлетворяющее условию /0,4f/<f</0,6f/, где f- фокусное расстояние мениска. Положительная линза выполнена плоско-выпуклой и обращена выпуклостью к мениску.The invention relates to an optoelectronic technique, in particular to optical systems of collimator sights, allowing you to accurately point a weapon at a target when firing in various lighting conditions. The optical system of the collimator sight contains a meniscus convex to the object of aiming, one of the surfaces of which reflects the radiation of the aiming mark. Between the meniscus and the aiming mark, displaced from the optical axis of the meniscus, a positive lens is inserted, made in the form of a lens fragment and installed from the meniscus at a distance d ', satisfying the condition aiming mark, while the positive lens has a focal length f that satisfies the condition / 0,4 f / <f </ 0,6 f /, where f is the focal length of the meniscus. The positive lens is made flat-convex and convex facing the meniscus.
