Author Affiliations +
The goal of this article is to describe the manufacture of lightweighted, 4 m diameter mirror blanks made of Zerodur in a fast and economical manner. Basic experiments have been performed involving production techniques and processes which may be usable to manufacture lightweighted mirrors in a mass-production format. On the basis of experiences gained through these experiments, a general consideration of the necessary equipment and further experimentation needed to develop the most promising of the processes will be described.
