Abstract
The Cherenkov Telescope Array (CTA) is the next-generation observatory for very high-energy gamma rays in the energy range from 20 GeV up to 300 TeV. It will consist of two arrays of imaging atmospheric Cherenkov telescopes of three different sizes. The CTA core energy range of 150 GeV - 5 TeV is covered with the Medium-Sized Telescopes (MSTs), whose segmented reflective mirror dish has a diameter of 12 m and is composed of 86 hexagonal mirror tiles. Here we present a final-design composite mirrors developed for MSTs jointly by the Institute of Nuclear Physics PAS in Krakow, CEA-Saclay and KERDRY Thin Film Technologies SMB enterprise, in collaboration with DESY-Zeuthen. The mirrors are made with the cold glass slumping replication technology. We present features of the mirror substrate design, mirror production technology and results of optical performance tests of the recently manufactured full-size mirror pre-production series.
