SUBSTRATE WITH LIGHTWEIGHT STRUCTURE

摘要

The invention relates to a monolithic substrate preferably comprising glass or glass ceramics, wherein the substrate has a lightweight structure, and to a method for manufacturing same. The lightweight structure comprises recesses which are delimited by webs, such webs forming tetragonal or four-corner-shaped pockets. Due to the lightweight structure, the weight of the substrate can be significantly reduced, and at the same time a high rigidity can be ensured. The substrate is preferably used as a mirror support or a mirror and can be employed terrestrially and/or extra-terrestrially. (Fig. 1)
