Design and Manufacturing of Optical Assemblies for High-End Electro-Optical Systems: Key Issues and Challenges

Shay Joseph, Evyatar Kassis, Arit Sheinmann

Rafael Advanced Defense Systems Ltd, Israel

The continuous pursuit to improve system performance is usually challenged

by key production issues rather than design issues. Enabling to fulfill the

seemingly impossible design specifications requires not only cutting edge

equipment but also innovative research and development processes.


11:30 - 11:45

Opto-thermo-mechanical simulation and automated robust design optimization of a lens system

Stephanie Kunath1, Daniel Asoubar2, Heiko Schüler3

1Dynardo GmbH, Germany; 2LightTrans International UG; 3CADFEM GmbH

A coupled, automated thermo-mechanical optical simulation of a lens system is presented. Its optical performance due to thermal effects and a mechanical deformation induced by the lens mounting is evaluated. A Robust Design Optimization is performed meaning that the optimizer is considering the robustness as well as the optimization criteria. With this method an optimized and robust design in terms of input tolerances is obtained in a fully automated manner.


11:45 - 12:00

Design of refocusing system for a high resolution spaceborne TDI CCD camera with wide-field of view

Shiliang Lv, Jinguo Liu

Changchun Institute of Optics, Fine Mechanics and Physics, Chinese Academy of Sciences, China, People's Republic of

This paper describes the design and realization of a refocusing system for a space TDICCD camera of 2.2-meter focal length, which, features a three mirror anastigmatic(TMA) optical system along with 8 TDICCDs assemble at the focal plane, is high resolution and wide field. TDICCDs assemble is a major method of acquiring wide field for space camera. In this way, the swath width reach 60km. First, TMA optical system and its advantage of this space camera was introduced; Then, the refocusing system as well as the technique of mechanical interleaving assemble for TDICCDs focal plane of this space camera is discussed in detail, At last, the refocusing system was measured. Experimental results indicate that the precision of the refocusing system is ±3.11µm(3σ).


12:00 - 12:15

Spaceborne multiband UV atmospheric detector with two fields

Qing-Sheng XUE1,2, Xiao-Heng WANG1,2

1Changchun Institute of Optics, Fine Mechanics and Physics, Chinese Academy of Sciences; 2University of Chinese Academy of Sciences

This paper designed a multiband atmospheric detector with two fields, on that basis, a prototype system has been completed. This prototype can detecting 10 degrees of front view and limb view in 360 degrees at the same time. The theory and prototype provides technical foundations for the further atmosphere remote sensing.


12:15 - 12:30

Novel high absorption ceramic coating made by plasma-chemical oxidation

Ulrich Peter Hausmann1, Martin Gabl1, Jürgen Schmidt2

1Swarovski Optik KG, Austria; 2Innovent e.V. Technologieentwicklung Jena, Germany

Stray light is a critical problem for high performance optical systems. It leads to a degradation of image or beam quality through artefacts, non-uniformities or unwanted heating effects.

Anodized mounts and housings remove stray light at large incident angles. However, unwanted reflections at grazing incidence angles (< 10°) still reach the sensor or process chamber.

A novel ceramic coating made by plasma-chemical oxidation (PCO) was developed for stray light suppression at grazing incidence angles. The pure ceramic coating provides high LIDT (laser induced damage threshold). It is scratch and corrosion resistant as well as RoHS and REACH conform.


12:30 - 12:45

Experimental study on spectral attenuation at low visibility artificial fog in visible and near infrared band

Aki Mäyrä, Eero Hietala, Matti Kutila

VTT Technical Research Centre of Finland Ltd, Finland

The EU-funded RobustSENSE project focuses technologies and solutions for automated driving in all environmental conditions. This report briefly summarizes the results of a literature survey and experimental measurements on spectral attenuation at low visibility artificial fog in visible and near infrared band.
