v531 v532 31 31 || '''21.03.2022''' || '''Markus Feldt''' || '''SPHERE+[[BR]][[BR]]'''Since 2015, SPHERE has been providing regular data and has not only enabled the consortium of manufacturers to produce well over 100 publications, but has also actually delivered transformative discoveries in the field of exoplanets and planet-forming disks. In one respect, however, its success has been limited: The instrument, which was conceived as a "planet hunter", has found planets, but the ultimate success has - foreseeably - failed to materialise, despite an enormous amount of observation time. However, 6 years of experience provided valuable information about the limiting factors, which have now been reliably identified, as well as possible remedies. This gave rise to the idea of a "SPHERE+" upgrade - an improvement in spectral resolution, as well as an upgrade of the XAO system with a second stage.[[BR]][[BR]]Presentation: German[[BR]][https://svn.mpia.de/trac/gulli/att/raw-attachment/wiki/WikiStart/att-sphere_plus.pdf Slides: English][[BR]]Questions: German, English || 32 32 || 28.03.2022 || -- || -- || 33 || '''04.04.2022''' || '''Andreas Bichler (!OptoSigma)''' || '''!OptoSigma - From University partner to space explorer'''[[BR]][[BR]]!OptoSigma (jap.: !SigmaKoki) is a global leader in developing and manufacturing high-quality photonic components.

MICADO can operate in a stand-alone mode where the ELT focal plane is reimaged to the MICADO focal plane via the relay optics (RO). This subsystem consists of an optical bench made of carbon fiber reinforced plastic, the MICADO calibration assembly, a cover to protect all opto-mechanical components on top of the bench, and an optical assembly. [[BR]] [[BR]]André Boné will present the optical design of the MICADO relay optics, and its tolerance analysis. These tolerances affect the WFE, the exit pupil quality, and optical distortion. The considered effects are alignment (internal and external), optical manufacturing tolerances, and mechanical effects such as mount-induced aberrations, warping of the supporting bench, and the thermal behavior of the subsystem. We will look into how these analyses are performed, and walk through some pros and cons of solutions that bring the system into compliancy.[[BR]][[BR]] Presentation: English[[BR]]Slides: English[[BR]]Questions: English ||36 || '''25.04.2022''' || '''André Boné''' || '''Tolerance studies for the Relay Optics of MICADO[[BR]][[BR]]'''MICADO is the Multi-AO Imaging Camera for Deep Observations, a first light instrument for the Extremely Large Telescope (ELT).
