Euclid is a space telescope currently developed in the framework of the ESA Cosmic Vision 2015-2025 Program. It addresses fundamental cosmological questions related to dark matter and dark energy. The lens system of one of the two scientific key instruments [a combined near-infrared spectrometer and photometer (NISP)] was designed, built-up and tested at the Max Planck Institute for Extraterrestrial Physics (MPE). We present the final imaging quality of this diffraction-limited optical assembly… 
Euclid warm testing of the near-infrared optical assembly using a unique combination of CGH interferometry and tactile precision measurements
The ESA Cosmic Vision “Euclid" mission will conduct a 6-years long survey of 15,000 square degrees of the sky to a look-back time of 10 billion years, with the aim of characterizing the matter-energy

Final tolerancing approach and the value of short-cutting tolerances by measurement
Within the ESAs 2015 - 2025 Cosmic Vision framework the 1.2 m aperture EUCLID space telescope addresses cosmological questions related to dark matter and dark energy. Being equipped with two
The EUCLID NISP tolerancing concept and results
TLDR
A new iteration of the baseline tolerancing concept for EUCLID NISP, with all 7 operational modes being low resolution slit-less spectroscopy and three band Y, J& H+ band photometry are being toleranced together is presented.
History and principles of Shack-Hartmann wavefront sensing.
TLDR
Enhanced images of satellites are enhanced by inserting a beam splitter in collimated space behind the eyepiece and placing a plate with holes in it at the image of the pupil, which captures a snapshot of the atmospheric aberrations rather than to average over time.
Diffractive optics for precision alignment of Euclid space telescope optics (Conference Presentation)
We present a method for precise alignment of lens elements using specific Computer Generated Hologram (CGH) with an integrated Fizeau reference flat surface and a Fizeau interferometer. The method is
Multi-zonal computer-generated holograms for high-precision optical adjustment purposes: part I: sensitivity and optical performance.
TLDR
The basic idea for alignment with MZ-CGHs is reviewed and the analytic relation between the interferometrically observed tilt and power values and the associated lens placement errors are derived, including estimates of the applied approximations.
