Abstract: The present invention is related to a method of manufacturing a mirror. The objective of the present invention is to propose very thin, mechanically and thermally stable minors with excellent surface properties as well as a manufacturing process for such minors. The method of manufacturing a minor in accordance with the invention comprises the steps of: (a) Providing a mandrel having the negative shape of the minor; (b) Applying a reflecting layer of reflective material on the mandrel surface; (c) Applying a bonding layer of bonding material on the reflective material; (d) Applying a structural layer of structural material on the bonding layer; and (e) Releasing the mirror from the mandrel. In particular, the reflecting material may be Gold, Iridium, Rhodium or Nickel, the bonding material may be Nickel, Nickel Cobalt or Nickel alloys, and the structural material may be Titanium or Titanium alloys.
