8: Mirror set one

The mirrors that are included in the system has a very high reflectivity, better than 99.5% Göran enlighten me. They are of two types, the flat one is used to redirect the light beam, and the parabolic divergent and focuses the light beam. The mirror together serves as a relay lens with 1: 1 ratio.
