Paper Abstract
If an ultra-thin mirror with 2-4mm thickness is applied on deployable space optical system, the mass of the system can
be decreased while its diameter increasing, and the mirror surface active adjust is achievable. The advantage of the
ultra-thin mirror compared with traditional light-weighted mirror described above make ultra-thin mirror a strong
competitor for next generation space optical system. Many important institutions have researched on fabrication of
ultra-thin mirror. Contrary, the advantage of ultra-thin mirror application is just the disadvantage in the process of
fabrication. Because of the ultra thin thickness, large distortion will be caused by the pressure of grinding and polishing.
Also, the distortion caused by temperature alteration and stress can not be ignored. These will all affect the precision of
the surface and increase its fabrication difficulty. The factors will possibly cause surface distortion and relevant control
method in the process of fabrication and measurement are discussed in this article. &slasho;195mm and &slasho;340mm ultra-thin
mirror fabrication experiments are carried out and ameliorations of fabrication technology are summarized form these
experiments. Finally, a &slasho;500mm ultra-thin mirror has fabricated and the experiment of active adjust indicates that this
mirror can achieve acceptable surface quality.
