Оптическое устройство снабжено парой взаимно перемещаемых групп линз, которые расположены на общей оси, и элементом, не пропускающим свет, который находится между этими двумя группами линз и скреплен с ними. Элемент, не пропускающий свет, представляет собой тонкую и относительно длинную прямоугольную ленту, которая спирально свернута и образует множество витков. В растянутом состоянии витки перекрываются, предотвращая прохождение падающего света в пространство между группами линз. В то же время лента является упругой, так что она поддерживает расстояние между этими двумя группами линз.The optical device is equipped with a pair of mutually movable groups of lenses, which are located on a common axis, and an element that does not transmit light, which is located between these two groups of lenses and is attached to them. An element that does not transmit light is a thin and relatively long rectangular ribbon that is spirally coiled and forms many turns. In the stretched state, the coils overlap, preventing the passage of incident light into the space between the groups of lenses. At the same time, the tape is elastic, so that it maintains the distance between these two groups of lenses.
