Abstract
A method for the production of mirrors entails performing a preliminary controlled pre-deformation treatment of an optical system, consisting of the following phases: calculation of the deformation of the optical system due to a selected reflecting treatment; design of a deforming layer such as to produce on the optical system a deformation opposite to the one caused by the selected reflecting treatment; and deposition on the optical system of a deforming layer on which the selected reflecting treatment will subsequently be deposited.
Claims4
A method for the production of a mirror, the mirror comprising an optical system and a reflecting treatment made up of one or more layers of selected materials deposited on a surface of the optical system;
- said method being characterised in that it comprises a preliminary controlled pre-deformation treatment of said optical system comprising the steps of:
- determining the deformation of the optical system caused by the selected reflecting treatment;
- designing a deforming layer such as to produce on said optical system a deformation opposite to the determined deformation caused by said selected reflecting treatment;
- and
- depositing said deforming layer on said optical system, on which said selected reflecting treatment will be subsequently deposited.
