Embodiment 1

[0014] See attached figure 1 , the reflective optical system multi-block reflectors share a mirror body structure and include reflective surface A1, reflective surface B4 and mirror body 5; said reflective surface A1 and reflective surface B4 are arranged on said mirror body 5, said reflective surface A1 and The reflective surface B4 protrudes from the mirror body 5 by a certain distance, and there is an empty knife 3 between the reflective surface A1 and the reflective surface B4, and the empty knife 3 is provided with an assembly process hole 2 at the position of the optical axis.

[0015] The mirror A and the mirror B are at least within the effective aperture range of the optical system.

[0016] The material of the mirror A and the mirror B is SiC material.

[0017] The adjustment process hole 2 is located on the optical axis.

[0018] See attached figure 2 , the mirror A and the mirror B are respectively used as the primary mirror and the third mirror in the three-re...

Embodiment 2

[0020] The difference between this embodiment and Embodiment 1 is that: the mirror A and the mirror B serve as a secondary mirror and a folding mirror in a three-reflection astigmatism (TMA) optical system, respectively.

Abstract

A reflective optical system with a mirror body structure shared by multiple reflectors belongs to the field of aerospace optics and aims to solve the problem of difficult back support of a single reflector in the prior art. The present invention includes at least two reflective surfaces and a mirror body; the reflective surfaces are all arranged on the mirror body, and an empty knife is left between adjacent reflective surfaces, and the empty knife is provided with an assembly process at the position of the optical axis hole. The present invention adopts a structure in which multiple reflectors share one mirror body, realizes multi-point support of a single mirror body, improves the aspect ratio of a single mirror, and widens the field of view of an optical system; The mirror support realizes the miniaturization and light weight of the telescope; each reflective surface meets the requirements of the optical system through optical processing; the stability of the optical system is improved and the difficulty of optical system assembly is reduced; the characteristics of the high thermal conductivity of the mirror material SiC material are utilized, Enhance the temperature adaptability of the optical system or mirror.

Description

technical field [0001] The invention belongs to the technical field of aerospace optics, and in particular relates to a reflective optical system with a mirror body structure shared by multiple reflectors. Background technique [0002] In order to achieve the purpose of wide field of view imaging of the telescope, the optical system telescope adopts strip mirrors; the aspect ratio of the mirror is too large, which is not conducive to the support of the mirror. In order to realize the purpose of miniaturization and light weight of the telescope, the size of each mirror Small; due to the small size of the single mirror body of the reflector, it is not conducive to the implementation of the back support structure. Contents of the invention [0003] The object of the present invention is to propose a reflective optical system with multiple reflectors sharing one mirror body structure, so as to solve the problem of difficulty in supporting the back of a single reflector in the ...
