Vector Apodizing Phase Plates for the ELT: From prototype to final optics for METIS and MICADO
J. A. van den Born, R. Landman, D. S. Doelman +12
The first generation of instruments for the upcoming Extremely Large Telescope (ELT) will allow for the direct imaging of exoplanets that were previously below the sensitivity or r…
SUPPPPRESS: Prototyping and testing liquid-crystal vector vortex coronagraphs with reduced polarization leakage
Rico Landman, David Doelman, Jeroen Rietjens +16
The vortex coronagraph is one of the most promising candidates for the Habitable Worlds Observatory (HWO) due to its excellent theoretical performance for an off-axis telescope. A…
METIS high-contrast imaging: from final design to manufacturing and testing
Olivier Absil, Matthew Kenworthy, Christian Delacroix +21
The Mid-infrared ELT Imager and Spectrograph (METIS) is one of the first-generation scientific instruments for the ELT, built under the supervision of ESO by a consortium of resear…
The MICADO first light imager for the ELT: off-axis performance of PSF reconstruction
Matteo Simioni, Daniel Jodlbauer, Carmelo Arcidiacono +14
The highest scientific return, for adaptive optics (AO) observations, is achieved with a reliable reconstruction of the PSF. This is especially true for MICADO@ELT. In this present…
The MICADO Atmospheric Dispersion Corrector: Optomechanical design, expected performance and calibration techniques
J. A. van den Born, R. Romp, A. W. Janssen +5
The differential refraction of light passing through the atmosphere can have a severe impact on image quality if no atmospheric dispersion corrector (ADC) is used. For the Extremel…
Demonstration of an imaging technique for the measurement of PSF elongation caused by Atmospheric Dispersion
J. A. van den Born, W. Jellema, E. Dijkstra
Elongation of the point spread function due to atmospheric dispersion becomes a severe problem for high resolution imaging instruments, if an atmospheric dispersion corrector is no…
