Abstract

The ESO-VLT is based on the combination of four 8m telescopes so as to provide a 16 m equivalent aperture. Two main possibilities for the manufacture of the mirror blanks are considered: a zero expansion glass ceramic from Schott and a lightweight steel structure. Manufacturing possibilities for both options as well as European industrial potentialities for the optical figuring are being reviewed. Results of the analysis of a particular honeycomb structure for the steel mirror and experimental data obtained on several test mirrors are presented.
