Objectives
Generally improving the development process of industrial optical systems with respect to stray light specification and control by standard procedures.
State of progress
Main activities were focused onto selecting recommendations for standard procedure updates. Recommendations are based on a state of the art analysis made before and taking into account actual results of a round-robin experiment among project partners. Special samples and handling procedures for that round-robin experiment were produced. As a result of work there is a software code, used to set up a data base and to import external existing stray light measurement data records. Beside different data base query functions, a link between the output data available from the database to ASAP(Advanced Systems Analysis Program), the commercially available de-facto industry standard software for stray light modelling, is established. The strategy was to convince the ASAP manufacturer, to adapt the ASAP interface to our proposed database output. This was achieved by inviting the head of the entire BRO to attend a international topical workshop entitled: "ASAP stray light simulation using experimental input data ...", held in Stockholm in conjunction with the SLiOS project progress meeting. BRO also relayed this information to the biggest commercial stray light database builder. Their database is now advertised as ASTM formatted. This in turn will most probably lead to that all future stray light analysis/modelling tools will be adapted to the ASTM format in the future. The conclusion is that the SLiOS project has successfully initiated a standardisation of the interface between experimental stray light data stored in the ASTM format and the input of forthcoming versions of the ASAP program.
As "state of the art analysis results" were established overviews regarding "Manufacturing Technologies and Modern Materials in use for production of low scatter optical components". First, the traditional fabrication method for manufacturing optical components is summarised. Then, other shaping and surface finishing methods are briefly discussed; Fabrication technologies for micro-optics are described as well as cleaning and storage techniques, monitoring techniques and modelling techniques for particle contamination.
To check, in how far design and measurements could be predicted by state of the art modelling, ASAP has been used for the stray light analysis of a selected test-bed. Even state of the art modelling software has difficulties to describe scattering sufficiently. We have learned that especially for coherent source applications predictive modelling of the stray light aspect in optical systems still remains very tedious. During the course of the project it was observed, that modelling software is advancing rapidly, but it will take a while until intensity distributions influenced by (near angle) scattering can be predicted accurately.

Background
Stray light is a source of noise in optical instruments. It causes degradation of imaging quality in imaging instruments and dedicated industrial optical systems for automatic optical measurement and optical exposure. Therefore, the control of the stray light level in the design, engineering and production of optical instruments is of importance to a wide variety of European industries.
Workprogramme
The technical work programme of the project was divided into five major work-packages (WP) aiming on Creation and validation of reliable material data (WP1100), Study of contamination effects (WP1200), Investigation of modelling (WP1300), Standard procedures for stray light definition and measurement (WP1400), Stray light test bed (WP1500).
