Abstract: The necessity of lightening the weight of the mirror for spaceoptical instrument is stated in this paper.The selection of material andstructure of lightweight mirror is also discussed.The deformation oflightweight mirror resulting from the external forces acting on it iscalculated using the finite element method.Finally the performances of theweight-lightened mirror are described.
