Description

II

Изобретение относитс  к оптическому приборостроению и предназначено дл  использовани  в астрономических инстру ментах.This invention relates to optical instrumentation and is intended for use in astronomical instruments.

Известные различные конструкции зеркал, которые с целью уменьшени  ве«са вьтолнены не монолитными, а с полост ми , образованными в теле зеркала М Прототипом  вл етс  зеркало, содержащее пластину с отражающей поверхностью , пластину-подложку, боковую обечайку и пакет  чеистых сот 23 ..The various designs of mirrors are known, which, in order to reduce their size, are not monolithic, but with cavities formed in the body of mirror M.

Недостатком таких конструкций  вл етс  наличие значительного количества элементов структуры, а следовательно, и мест соединени , что усложн ет технологию изготовлени  и снижает жесткость конструкции. Поскольку соединение сфер между собой осуществл етс  при спека- . НИИ, то отсутствует возможность контрол  качества соединений элементов структуры между собой. Заготовки зеркала получают с дефектами соединений структуры.The disadvantage of such structures is the presence of a significant number of structural elements, and hence the joints, which complicates the manufacturing technology and reduces the rigidity of the structure. Since the spheres are interconnected with each other during sintering. Institute, then there is no possibility to control the quality of the compounds of the elements of the structure among themselves. Mirror blanks are obtained with defects in the structure's joints.

Целью изобретени  5шл етс  повышение жесткости зеркала и уменьшение деформаций .The aim of the invention is to increase the rigidity of the mirror and reduce deformations.

Эта цель достигаетс  тем, что сотовый пакет выполнен в виде, по крайней мере, одного р да соединенных между собой полых герметичных сфер и цилиндров.This goal is achieved by the fact that the cellular package is made in the form of at least one row of interconnected hollow hermetic spheres and cylinders.

На фиг. 1 изображено зеркало, продольный разрез; на фиг. 2 - разрез фиг. 1; на фиг. 3 - разрез отдельного FIG. 1 shows a mirror, a longitudinal section; in fig. 2 is a sectional view of FIG. one; in fig. 3 - section of a separate

Зеркало состоит из пластины-зеркала 1, пластины--подложки 2, с дренажными отверсти ми 3, боковой обечайки 4, и, по крайней мере, одного р да полых гер- The mirror consists of a plate-mirror 1, a plate-substrate 2, with drainage holes 3, a side shell 4, and at least one row of hollow tubes.

15 к|.етичных, элементов структуры, состо щей из сферических и цилиндрических 5 f и В элементов, соединенных между собой.15 to | t., Structural elements consisting of spherical and cylindrical 5 f and B elements interconnected.

Отдельные элементы структуры получают из трубок заданного диаметра пу20 тем локального нагрева и выдувани , в результате чего шрлучают элементы с г чередованием сферических и цилинд|эических элементов, соединенных между собой.Separate elements of the structure are obtained from tubes of a given diameter by means of local heating and blowing, as a result of which elements are formed with r alternating spherical and cylindrical elements interconnected.
