“…Goodman and Jacoby compared some characteristics of conventional webs and foam cores for mirrors, as indicated in Table 6 [53]. Goodman et al [54][55][56][57] used silicon foam which can be machined to any shape (sphere, asphere, etc.) to manufacture the silicon lightweight mirror (SLM).…”

With the continuous improvement of the imaging quality requirement of the space optical system, the large-aperture mirror becomes the research focus. However, the increase of the aperture will increase the whole weight which results in high launch cost and degrades the mirror surface figure accuracy. Therefore, the lightweight design method of the mirror structure is of great importance. In recent years, many space telescope system schemes have demonstrated the progress of the structural lightweight design of mirrors, such as Spitzer, SOFIA, JWST, etc. This article reviews the main content and innovations of the research on the structural designs of mirrors including conventional machining designs and topology optimization structures. Meanwhile, some emerging designs (e.g., lattices and Voronoi structures) considering additive manufacturing (AM) are also introduced. Several key elements of different structural design approaches for lightweight mirrors are discussed and compared, such as material, lightweight ratio, design methods, surface figure, etc. Finally, future challenges, trends, and prospects of lightweight design for mirrors are discussed. This article provides a reference for further related research and engineering applications.

“…29 Carbon fiber reinforced silicon carbide composites have been used as instrument housings because of its stability, stiffness, and tailorable CTE. 30 During and immediately after WWII, the material most frequently used to seal optical instruments was a polysulfide called EC801. It served as filler in the gaps between windows or lenses and the instrument housings.…”

We recall how techniques for optical and mechanical design, engineering and fabrication have evolved during the 60-year period since the end of World War II. Considerations include some ways in which improvements in materials availability and in methods for design, analysis, tolerancing for fabrication and alignment, and hardware assembly, inspection and environmental testing may have facilitated development of increasingly sophisticated optical instruments.
