Abstract: A process for manufacturing by moulding an optical component includes at least the following steps: a step of providing at least one mould, during which a glass profile is provided, said glass profile including a doping according to a predetermined geometry and having a refractive index profile depending on said doping and including at least an end including at least a structuring obtained by chemically etching of said doping, said structuring forming said at least one mould, and a moulding step, during which at least a moulding material suitable for forming at least an optical component is provided and arranged in said mould in order to shape said optical component.

Abstract: A system of super-resolution full-field optical metrology for delivering information on the surface topography of a sample or object on the far-field nanometre scale, including a light source, an interferometer (1a, 1b, 1c, 1d) including a reference arm incorporating a micro bead and a mirror, an object arm including a micro bead similar to the micro bead and arranged in immediate proximity to the surface of the object, receiving structure for capturing the interference figures, and a processor for processing these interference figures in such a way as to produce surface topography information. The light source is temporally coherent or partially coherent. The interferometer and the processor for processing interference figures are designed to reconstruct the surface of the object by phase shifting interferometry.

Abstract: Disclosed is a laser treatment device and a workstation including such a device. The laser treatment device includes a laser head including an optical fiber terminating in a beam focusing end piece that is shaped from the free end portion of the fiber so as to form a single part therewith. The focusing end piece is rotationally symmetrical about an axis and has a shape defined externally by a substantially semi-elliptic convex curve of given dimensions, and the distance d between the tip of the focusing end piece and the working area, and the shape and positioning of the end piece are such that the laser head generates a slightly divergent, focused laser beam in the form of a photon jet, having a diameter at the working area of the order of magnitude of the wavelength.
