    Abstract: Composite mirror systems include a wideband thin film interference stack having a plurality of microlayers and an optically thick layer having a refractive index greater than air but less than the smallest refractive index of the stack. The mirror systems can provide high reflectivity for light propagating in the stack and in the optically thick layer at supercritical angles, while avoiding degradation in reflectivity if dirt or other disturbances such as absorbing materials are present at the mirror backside for example due to contact with a support structure.

    Abstract: A macroscopic mirror for wide angle scanning applications comprises: a silicon substrate section of a predetermined shape and macroscopic size cut from a silicon wafer comprising a flat, polished surface side and an etched, rough surface side; and a plurality of layers, including a layer of reflective medium, disposed on the flat, polished surface of the substrate section in such a manner to minimize flexural distortion of the flat surface. The macroscopic mirror is made by a method comprising the steps of: preparing the silicon wafer by polishing one side to a predetermined flatness and etching the other side to a predetermined roughness; cutting the substrate section from the prepared silicon wafer to a predetermined shape and macroscopic size; and applying the plurality of layers on the flat, polished surface. The macroscopic mirror is included in a mirror system wherein the rough surface side is bonded to supporting arms of a drive mechanism which scans the mirror at a predetermined scanning rate in at least one plane of rotation.

    Abstract: A multilayer mirror comprises a reflector section including a plurality of alternating layers of a high index material and a low index material, and a filter section over the reflector section. The filter section comprises a first filter layer including a low index material on a layer of high index material of the reflector section; a second filter layer on the first filter layer, the second filter layer comprising a high index material that is different than the high index material in the reflector section; and a third filter layer on the second filter layer, the third filter layer comprising a low index material. Each filter layer has an optical thickness greater than or equal to the optical thickness of each layer of the alternating layers. The filter section substantially blocks ultraviolet (UV) energy, thereby preventing UV energy from substantially impinging on the high index material of the reflector section.

    Abstract: The invention relates to a method for treating a mirrored optical item, comprising: a substrate (10), a mirroring stack (21) of at least two interference layers (M1 to M6) carried by the substrate (10), thus increasing the reflection and having: an interference layer (M1) distant from the substrate (10), with a first initial thickness and a first refractive index and at least one near interference layer (M2) arranged between the substrate (10) and the distant interference layer (M1), with a second thickness and a second refractive index different from the first refractive index, the mirroring stack (21) giving the mirrored optical ilem (1) a first colouring according to the CIELAB space, by means of an interferometry phenomenon, the method comprising a step (103) of removing, by ion bombardment, at least in one first predetemrined zone (Z1), a thickness of the mirrored stack that is less than the sum of the initial thicknesses concerned by the removal step, the mirrored optical item having, by means of an interferometry phenomenon, a second colouring according to the CIELAB space different from the first colouring.
