  • Patent number: 8496863
    Abstract: In a method for producing a replication master (10) having a surface with low roughness, comprising the steps of forming said master (10) such as to have a desired external surface shape corresponding to a counterform of a surface of an object (18, 20) to be produced by replication and treating said external surface of said master (10) to obtain a predetermined surface roughness value, it is proposed that said method furthermore comprises the step of coating at least a part of said master (10) with a soluble smoothening layer (16). The invention further relates to a replication master (10) for producing a smooth object (18, 20) having a low surface roughness, wherein at least a part of said master (10) is coated with a soluble smoothening layer (16).

  • Patent number: 7248670
    Abstract: The invention relates to an optical assembly with a laterally graded reflective multilayer whose reflecting surface reflects incident X-rays under low incidence angles to produce a two-dimensional optical effect. The reflecting surface comprises a single surface conformed along two curvatures corresponding to two different directions. The invention also relates to a manufacturing method of such an optical assembly. The method includes coating a substrate already having a curvature. The invention also relates to a device for generating and conditioning X-rays for applications for angle-dispersive X-ray reflectometry. The device includes the optical assembly connected to an X-ray source so that X-rays emitted by the source are conditioned along two dimensions so as to adapt the beam emitted by the source to the sample, with the X-rays having different angles of incidence on the sample under consideration.

  • Publication number: 20060018429
    Abstract: The invention relates to an optical device intended to treat an incident X-ray beam. The optical device comprises a monochromator and an optical element for conditioning the incident beam. The reflective surface of the optical element is able to produce a two-dimensional optical effect in order to adapt a beam in destination of the monochromator. The reflective surface of the optical element comprises a multilayer structure type surface that is reflective to X-rays. In particular, the reflective surface consists of a single surface shaped according to two curvatures corresponding to two different directions.

  • Publication number: 20050094271
    Abstract: One aspect of the invention relates to a multi-layered reflective optical system for the reflection of X rays at a low angle of incidence, producing a two-dimensional optical effect. The inventive optical system comprises: a component having a surface which is reflective in such a way that a first optical effect is produced according to a first direction in space; and means for producing a second optical effect according to a second direction in space which is different from the first direction, characterized in that said means for producing a second optical effect are borne by the reflective surface. A second aspect of the invention relates to a method for the production of said optical system.
