Abstract

In March 1990 a contract was signed between the `Osservatorio Astronomico di Padova' and CARL ZEISS Oberkochen to fabricate the Galileo optic, consisting of a 3.6 m Primary F12.2, the corresponding secondary and the flat folding tertiary. All three components are made from low expansion glass ceramic zerodur. The intrinsic quality of the complete optical train is specified with respect to the encircled energy: E 80% within 0.15 arcsec (phi) . The paper presents the results of the final interferometric tests.
