A manufacturing method creates a type of telescope which is athermal, lightweight, optical quality for visible and IR applications. The method includes: The master or mandrel can be cleaned and reused for repeating this method and manufacturing large series of telescopes.

Process for manufacturing an athermal low cost telescope based on high precision replication technology, and such telescope

An alignment tool for use in calibrating an optical bench and/or alignment of an optical system such as a collector optical system for EUV and X-ray applications is disclosed. The optical system includes multiple nested mirrors attached to a mechanical support. The tool includes a mechanical interface plate, a lower reference ring, an upper reference ring and a pinhole member disposed spaced apart axially in sequence; a first positioning device attached to the mechanical interface plate and to the lower reference ring; the first positioning device being adapted for precisely adjusting the position of the lower reference ring in two dimensions; a second positioning device attached to the mechanical interface plate and to the upper reference ring and adapted for precisely adjusting the position of the upper reference ring in two dimensions; a third positioning device attached to the upper reference plate and to the pinhole member and adapted for precisely adjusting the position of the pinhole member in three dimensions; a mechanical interface mounted on or integral with the mechanical interface plate and being substantially identical in form to that of the mechanical support of the optical system.

Optical alignment tool and method of alignment

Optical mirror elements for high bandwidth free space optical communication are produced by an electroforming replication technique. Onto the precision surface of a mandrel that is a negative of the required optical surface a layer of metal is deposited forming an exact copy of the mandrel surface and is then separated to form the required optical element. During the production process the mandrel may be coated with a variety of materials that are then separated together with the electroformed optical element during the release step to form a monolithic structure that includes a reflective coating. The mandrel remains unchanged by the process and can then be re-used. The high cost of conventional polishing techniques is therefore limited to the production of the mandrel. The replication process results in the production of low cost optical elements suitable for high bandwidth free space optical data transmission.
