The reflector of a Cherenkov telescope is composed of many individual mirror facets. In particular, for the MST, hexagonal mirrors of 1.2m (flat to flat) diameter will be used, with a spherical shape of about 32 m of radius of curvature. In order to fulfill the specifications on optical properties, mechanical behavior and costs, different technological solutions are under study Most of them involve a composite structure, supporting a slim reflective surface, which is assembled and glued using the cold slump technique .
