Device for supporting grating of space solar telescope

Abstract

The invention discloses a device for supporting a grating of a space solar telescope, and the device comprises a grating seat which is internally provided with a grating installation cavity in which a grating is embedded; and a bracket assembled and fixed with the grating seat. The bracket is connected with an external structure main body, and the grating seat is connected with the external structure main body through the bracket; the grating seat is obliquely arranged relative to the bracket, and a diaphragm is arranged at the upper part of the grating seat; and the diaphragm and the grating in the grating seat are arranged at an angle of 60 degrees. According to the device, positioning installation of the grating is achieved through the grating base, the support forming a certain angle with the grating base is used for being connected with an external main body structure, meanwhile, the characteristics of silicon rubber and distribution of two rows of glue injection holes are utilized, the grating and the grating base are pasted and fixed through D04 glue, and the problem that the smearing amount is too large or insufficient is solved; injected glue can be prevented from flowing out, and the mounting stability of the grating is improved.

Description

technical field [0001] The invention relates to the technical field of optical mechanical design, in particular to a grating support device for a space solar telescope suitable for installation of gratings and apertures. Background technique [0002] With the continuous development of science and technology, the demand for optical devices in the aerospace field is getting higher and higher, but sometimes the optical devices are too large or have poor stability while meeting the established requirements. The existing structure cannot guarantee that the expected demand can be met under the condition of small and stable structure. [0003] In recent years, micro-nano processing technology has become increasingly mature. Gratings and diaphragms have been widely used in the fields of optics and optomechanics. Various optoelectronic devices have become more miniaturized and integrated. Wide application has become a trend, and various optical elements made of various diffraction a...
