Final Mirror Production

In order to decrease the number off necessary mirrors the final mirror segment has radius of circumscribed circle 624.68 mm. It is about 25% more than radius of prototype on the picture. The number of mirror segments per one telescope is decreased from 85 to 60 pieces. Also the tesselation was simplified, instead of six different prototype mirror types only four types are necessary for the final configuration.
