Design and modelling of spectrographs with holographic gratings on freeform surfaces
Eduard R. Muslimov, Marc Ferrari, Emmanuel Hugot +6
In the present paper we demonstrate the approach of using a holographic grating on a freeform surface for advanced spectrographs design. We discuss the surface and groove pattern d…
SPHERE on-sky performance compared with budget predictions
Kjetil Dohlen, Arthur Vigan, David Mouillet +21
The SPHERE (spectro-photometric exoplanet research) extreme-AO planet hunter saw first light at the VLT observatory on Mount Paranal in May 2014 after ten years of development. Gre…
Curved detectors developments and characterization: application to astronomical instruments
Simona Lombardo, Thibault Behaghel, Bertrand Chambion +8
Many astronomical optical systems have the disadvantage of generating curved focal planes requiring flattening optical elements to project the corrected image on flat detectors. Th…
Design of optical systems with toroidal curved detectors
Eduard Muslimov, Emmanuel Hugot, Marc Ferrari +4
We consider using toroidal curved detectors to improve the performance of imaging optical systems. We demonstrate that some optical systems have an anamorphic field curvature. We c…
The adaptive optics modes for HARMONI: from Classical to Laser Assisted Tomographic AO
B. Neichel, T. Fusco, J. -F. Sauvage +25
HARMONI is a visible and NIR integral field spectrograph, providing the E-ELT's core spectroscopic capability at first light. HARMONI will work at the diffraction limit of the E-EL…
Spectrographs with holographic gratings on freeform surfaces: design approach and application for the LUVOIR mission
Eduard Muslimov, Marc Ferrari, Emmanuel Hugot +5
In the present paper we demonstrate the approach to use a holographic grating on a freeform surface for advanced spectrographs design. On the example POLLUX spectropolarimeter medi…
