Abstract
Substrate material is important while manufacturing of large-dimensioned optical mirrors for ground and space applications. The properties of Astrositall, its dimensional stability, design features are considered. Various types of supporting cells and optical components bases are used in the process of surfaces figuring. Applying of membranepneumatic support to base the mirror in the course of working surface testing is considered. However, in some cases it is necessary to support the mirror basing it on glued interface elements. In such case, surface figure difference between standard and manufacturing support cell, which is taken into account during figuring, is estimated via modeling.
