3-Day Course Optomechanical System Design Scope Optomechanical system design is a truly multidisciplinary expertise that combines optical, mechanical, mechatronic, thermal, electrical, control and systems engineering. It covers (mass) product development for the high-tech industry, where reliability and manufacturability are paramount, as well as advanced one-of-a-kind instruments for science and research, for which ultimate performance is the design objective. Achieving good optical system performance involves an integral approach of the optical and mechanical design during an iterative optimisation process. This requires the combination of both precision engineering and basic optical principles. The optomechanical engineer is not an optical designer, but he has to understand the impact of optical principles on system design and mechanics. Course Overview To promote optomechanical system design, DSPE has taken the initiative to organise a 3-day course that provides through introduction to this modern discipline. The course focuses on the mechanical and mechatronic design for optical systems and is intended for mechanical, mechatronic and optical engineers involved in optomechanical system design. It will also be a very valuable course for any engineer interested in optomechanical design approaches and solutions. The teachers will guide you through the diverse landscape of optomechanical system design. They will begin with the basics and show approaches and solutions for many design issues along the way. Together they draw upon more than 100 years of experience in this field at Dutch universities and research institutes and in the high-tech industry. In the curriculum a wide variety of design examples are used, focusing on the lessons of failure. Caleidoscopic experience The teachers are experienced engineers, who know the tricks of the trade in optomechatronics, system architecture, system design and engineering, and optomechanical engineering.

The system engineering aspects are presented in a practical fashion with many examples. Tools for evaluating tolerances and error budgets will be provided and discussed. Mechanics for optics In this part all practical design rules are presented with many examples of crucial hardware aspects Miscellaneous In this part ‘side issues’ are presented that can be become show stoppers in optomechanic system design, including cable routing and surface treatment. Alsoa worskhop on cryogenics is given. Programme Day 1 – From optics to opto-mechanics Morning Optical systems Basic understanding of the lay-out? of optical systems of components like optics, detectors, light sources Optics and positioning The effect of positional errors, of basic optical components, on the performance of an optical system. Mirrors are for example insensitive for in plane translations and rotations and sensitive for out of plane translations and rotations. Opposed to a lens which is sensitive for in plane translations and insensitive for out of plane rotations. Afternoon Tolerancing and alignment strategy Key factors in achieving optimal performance and cost of optical systems. This requires knowledge of optical and mechanical tolerancing. The opto-mechanical engineer plays an important role in determining the alignment strategy, Degradation The causes of signal degradation in optical systems. What is the effect of for example blur, vibration and flare on optical system performance. Opto-mechanics and system engineering We introduce the optomechanics interface table. All key characteristics of your optical systems shall be brought together in an overview at the start of your design process. Aspects as size, power and positioning or alignment accuracy and stability of all components. This is an essential first step of your opto-mechanical design process to realize an optimal opto-mechanical system. Evening Informal diner in the centre of Eindhoven Day 2 – Mechanics for optics Morning Alignment mechanism Experience inthe design of alignment mechanisms is crucial for accurate and stable initial positioning of optics,Basic mechanism concepts for standard optomechanical systems are presented. A variety of dedicate mechanism designs and commercial available mechanisms is presented. Aspects like alignment screws selection or design of minimal drift lockings are relevant for optimal design or selection of alignment mechanism Stability Focus is on thermal stability of optical systems. Starting with the importance of statically determined design rules. Athermal design principles such as the thermal centre or thermal compensation are presented. Design aspects of highly stable base structures, the ‘metroframes’ are part of the course. Afternoon Dimensional stability of materials This topic is prominently present in Optomechanical system design. Release of internal material stresses lead to drift. Causes of drift due to stresses during machining is discussed as well ascomplex material structures like invar or zerodur A wide variety of characteristics and tables are presented. Mounting of optical components Typical characteristics of many ‘optical’ materials is the fact that they are brittle. This strongly determines the design of optical mounts. Understanding of material characteristics as well as a variety of optics mounting guidelines are presented. Two basic approaches are discussed, mechanical clamping and gluing of optics Day 3 – Miscellaneous Morning Potential show stoppers Presents the aspects, which you easily forget, but are so important for successful optical system: Cable routing in optical instruments Opto-mechanical surface treatments: In many optical systems the structural parts require dedicated coatings to avoid unwanted optical effects like stray light. Afternoon Cryogenic infrared instrumentation This workshop is devoted to the special topic of optomechanics in cryogenic environments, and covers.
