Optics packaging Technologies for harsh environment - Erik Beckert
Not only the design, but also the packaging of optical systems is a key factor for highly performant and reliable, robust systems. This is of interest in particular in harsh environments, such as aviation and space, but also vacuum science and high power laser machining. Packaging of optical systems poses various challenges - different materials have to be joined together, components and their optical performance are stress and alignment sensitive, heat from active sources and conversion materials needs to be dissipated, and steep temperature gradients causing thermomechanical stress can occur. Well designed and optimized packaging and bonding technologies address these needs.
The talk will focus on bonding techniques for metallic and non-metallic, amorphous and crystalline materials, emphasizing on the development and application chain from bonding geometry design, optimization by simulation of stress and the resulting birefringent or laser-optical performance, and practical issues of processing and equipment when applying different bonding technologies. Specific technologies to be discussed are gluing, soft soldering by means of laser reflow, hydrophilic bonding and plasma assisted bonding as well as two-photon absorption based laser welding. The basics as well as design and parametrization of these techniques will be discussed, followed up by boundary conditions and restrictions. Examples will demonstrate the application of the different technologies in reality. Amongst them is the green laser for the Raman experiment of the upcoming 2020 ExoMars Mission, a nanosecond fiber laser for a space LIDAR and an entangled photon source for a satellite quantum payload.

Lecturing: Freeform Optics

One of my very first large scale projects in optics was the design of the optics for SPOT4 (Satellite Pour Observation de la Terre), put in orbit March 24 1998 and operational till July 2013. Since, my interest in optical instrumentation has spanned a wide range of applications with a focus on head-worn display for the consumer market, microscopy, and space optics. In 2013, as a faculty at the University of Rochester, NY I led the launch of the National Science Foundation (NSF) Center for Freeform Optics (CeFO) headquartered in Rochester, NY, targeted at advancing the science and engineering of freeform optics across a wide range of applications, including space optics, in partnership with industry and government ( Today my main research activities lie in optical system design and metrology of freeform optics.

Freeform Optics Verification - Christopher Evans
This series of lectures will start from fundamentals -- calibration, uncertainty and traceability in freeform optics metrology. Design intent should be captured in the specification of the optic, for example in a drawing that is in accordance with ISO 10110. We will discuss freeform optics specifications that flow down to measurands that can be estimated en route to establishing that a specific optical surface meets the design intent. Does the designer have a specific manufacturing process in mind? Can this be captured in the surface specification -- and should it be? We will review the range of optics metrology methods available and discuss tools for rational comparison between available options. "Design for Metrology" will be a central theme. We will review commercially available technologies and emerging methods.

Gratings are key components in space-borne spectrometers for earth observation and scientific missions. Their optical properties determine the achievable spectral resolution and signal quality of the instrument. Based on the specific requirements of contemporary spectrometers an overview of state-of-the-art fabrication technologies for the required high-end optical gratings will be given. This includes methods like ruling, holography, and direct write lithographic structuring. Their potential and limitations for the realization of a desired grating profile and related properties like high polarization independent diffraction efficiencies, good wave-front qualities, and low stray-light levels will be discussed. Different examples of gratings tailored for specific ESA space missions like GAIA, Sentinel-4/5, or DESIS will be shown.

Polarization Scrambler – Concepts, Optical Design, Manufacturability and Performances - Jerome Caron
Polarization scramblers are optical devices that depolarize light, and alter as little as possible light propagation so that they can be used in imaging instruments. Scramblers from the class of spatial pseudo-depolarizers are compact, passive components with high performance that are well suited for space applications. They have (or are currently) been built for several spectro-imagers to make the measurements insensitive to polarization: OMI, Envisat/Meris, Sentinel-3/OLCI, Sentinel-4/UVN, Sentinel-5p/Tropomi, Sentinel-5. In this course we will present their design, performance, manufacturing and testing. The Dual Babinet [1] is the most important design and will be assumed for the general discussion. Other types such as the HV depolarizer, the Meris scrambler, the plane-parallel scrambler and a few recent patents will be also presented.

Optically Rough Surface Scatter Measurements and Modelling - Monika Kroneberger
Light scattering caused by the imperfections of optical and mechanical surfaces can critically affect the performance of space optical instruments (image quality, losses). It is therefore very important to predict and measure stray light performance of the optical instrument accurately.
This lecture is focusing on light scattering of mechanical surfaces and of diffusers. Special emphasis will be put on how to measure and model optically rough surface scatter. A second part will focus on the minimization of mechanical surface scatter by "black"coatings and a review of achievable performances.

Structural-Thermal-Optical Performance (STOP) Analysis of the Euclid Space Telescope - Sergio Mottini
Success of ESA’s Euclid cosmology mission depends on the stability of the telescope under loads transmitted from its environment, including the spacecraft bus. STOP analysis is the tool used to verify compliance with the tight image quality budgets of the focal plane instruments. The analysis proceeds through three coordinated sets of mathematical models to calculate, in sequence, temperature distributions, displacement and/or distortion of the optical elements, point spread functions at selected locations on the focal planes, and the resulting optical figures of merit. After a brief presentation of the mission objectives, the telescope and satellite design, and the environmental boundary conditions, the lecture will describe in some detail the procedure adopted, the results achieved and the lessons learnt at the time of the project’s Critical Design Review.

AIT of On- and Off-axis telescopes - Matthias Erdmann
The optical alignment of the telescope is a key activity of the AIT process of On- and Off-axis telescopes. The method described and practiced in the lecture is based on the fact that any alignment activity (shifting and tilting of optical elements) influences only the low order aberrations of the optical system. For the alignment the Wave Front Error (WFE) of the telescope is measured (e.g. by auto-collimation) and decomposed in low order aberration contributions. Based on analysis of the as-built model of the telescope and probing of the pre-aligned telescope optics sensitivities of low order WFE contributions to all optical alignment Degree Of Freedoms can be evaluated. Based on these sensitivities the next step of alignment improvement can be calculated, executed and verified. Recursive application of these technique converges to a perfect optical alignment after two or three iterations. For Korsch type telescopes including Three Mirror Anastigmats (TMA) the typical aberration and aberration sensitivities field gradients are discussed and their utilisation for the alignment is described and practiced.
