In recent years, metal mirrors have grown in popularity. Many short courses and papers have discussed the mechanical properties and calculated rigidity and thermal performance of mirrors. This presentation will briefly touch on these but give more emphasize on metal mirror fabrication procedures, material comparisons, and cost. Fabrication procedures for aluminum, metal matrix composite (MMC), beryllium (five classes) and glass mirrors are given. Procedures should be used only as a starting point since they vary from part to part.
