3-DAY COURSE Optomechanical System Design
On March 9, 10 and 11 we will repeat the course because of the great interest there was in October 2019 during the Optics Week.
Investment 1200 euro excluding VAT.
Registration is required.
Maximum of 25 participants.
Location: BCN Eindhoven, Kennedyplein 204 (near railwaystation Eindhoven)
Registration form below.
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. The teachers are experienced engineers, who know the tricks of the trade in optomechatronics, system architecture, system design and engineering, and optomechanical engineering. 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.
The= teachers are experienced engineers, who know the tricks of the trade in optomechatronics, system architecture, system design and engineering, and optomechanical engineering.

Day 1 – From optics to opto-mechanics
• 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.
• 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,
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.

Day 2 – Mechanics for optics
• 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. An example is presented.
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. An example of lumped mass modelling will be presented.
• 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
• 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.
• Cryogenic infrared instrumentation
This workshop is devoted to the special topic of optomechanics in cryogenic environments, and covers.
• Astronomical science (briefly)
• Discussion on the specific environment as encountered for this type of instrumentation
• Engineering challenges imposed by these environments
• Challenges and design solutions for:
• Optics mounting (mirrors, lenses, prisms, gratings, grisms, filters)
