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…
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…
Bringing high-spectral resolution to VLT/SPHERE with a fibre coupling to VLT/CRIRES+
A. Vigan, G. P. P. L. Otten, E. Muslimov +9
Atmospheric composition provides essential markers of the most fundamental properties of giant exoplanets, such as their formation mechanism or internal structure. New-generation e…
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…
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…
Advanced optical designs of curved detectors-based two-mirrors unobscured telescopes
Eduard Muslimov, Emmanuel Hugot, Simona Lombardo +4
In the present paper we consider a family of unobscured telescope designs with curved detectors. They are based on classical two-mirror schemes -- Ritchey-Chretien, Gregorian and C…
Curved detectors for wide field imaging systems: impact on tolerance analysis
Eduard Muslimov, Emmanuel Hugot, Simona Lombardo +7
In the present paper we consider quantitative estimation of the tolerances widening in optical systems with curved detectors. The gain in image quality allows to loosen the margins…
POLLUX: a UV spectropolarimeter for the LUVOIR space telescope project
Eduard Muslimov, Jean-Claude Bouret, Coralie Neiner +9
The present paper describes the current baseline optical design of POLLUX, a high-resolution spectropolarimeter for the future LUVOIR mission. The instrument will operate in the ul…
Experimental study of an advanced concept of moderate-resolution holographic spectrographs
Eduard Muslimov, Gennady Valyavin, Sergei Fabrika +4
We present the results of an experimental study of an advanced moderate-resolution spectrograph based on a cascade of narrow-band holographic gratings. The main goal of the project…
