Method for the microdeformation of the front face of a thin part, by modifying the rear face or the periphery of the part. According to the invention, which can notably be used to correct the wave surface of a mirror, a local treatment is applied to the rear face or to the periphery which causes a static microdeformation, which is frozen once and for all, of the front face, without applying any mechanical force to the part.

Embodiments relate to a device for measuring characterisation by reflectometry including a source that emits a light beam, a detector, optics for processing and controlling this light beam so as to focus it on a reflective surface to be measured in the form of a spot and to receive it on the detector, command and acquisition modules, a camera and modules for imaging the spot on the detector and on the camera, wherein the camera is connected to the command and acquisition means so as to automatically focus the spot on the reflective surface to be measured and to automatically conjugate the reflective surface to be measured with the surface of the detector.
