Strength of Zerodur® for mirror applications

Autor: Sonia Ait-Zaid, Stéphanie Behar-Lafenetre, Laurence Cornillon

Publikováno v: SPIE Proceedings.

Zerodur® is a well-known glass-ceramic used for optical components because of its unequalled dimensional stability under thermal environment. In particular it has been used since decades in Thales Alenia Space’s optical payloads for space telescop
