Abstract

Decreasing mass of telescope mirrors issue is still actual today. Common lightweighting mirrors method uses relief back structure. In the article it is proposed to change back flat surface to spherical one. Options of mirror design are considered: design of "negative" (with the smallest thickness in the center), "positive" (with the smallest thickness along the edge) meniscus and meniscus with the same thicknesses. The schemes of mounting such mirrors in telescope are considered.
