3D printing for astronomical mirrors
Melanie Roulet, Carolyn Atkins, Emmanuel Hugot +3
3D printing, also called additive manufacturing, offers a new vision for optical fabrication in term of achievable optical quality and reduction of weight and cost. In this paper w…
Superpolished OAPs for WFIRST CGI
Melanie Roulet, Emmanuel Hugot, Carolyn Atkins +3
Exoplanet imaging requires super polished off-axis parabolas (OAP) with the utmost surface quality. In this paper we describe an innovative manufacturing process combining 3D print…
Use of 3D printing in astronomical mirror fabrication
Melanie Roulet, Carolyn Atkins, Emmanuel Hugot +12
In this paper we are exploring the possibilities of 3D printing in the fabrication of mirrors for astronomy. Taking the advantages of 3D printing to solve the existing problems cau…
Curved detectors for astronomical applications:characterization results on different samples
Lombardo Simona, Behaghel Thibault, Chambion Bertrand +8
Due to the increasing dimension, complexity and cost of the future astronomical surveys, new technologies enabling more compact and simpler systems are required. The development of…
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…
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…
