Upgrading LBTI/NOMIC with a quadruple annular groove phase mask and GeoSnap detector for imaging nearby, habitable-zone exoplanets
Kevin Wagner, Manny Montoya, Steve Ertel +32
The Large Binocular Telescope Interferometer (LBTI)'s Nulling-Optimized Mid-Infrared Camera (NOMIC) is among the most capable thermal-infrared imaging systems available for high-co…
Continuing to Advance European High Contrast Imaging Research and Development towards HWO and LIFE
Gael Chauvin, Oscar Carrion Gonzalez, Iva Laginja +20
The European Research and Development for Space based High Contrast Imaging II Workshop, held at MPIA in May 2025, advanced Europe strategic coordination in support of future exopl…
MIRAC-5 on the MMT with MAPS: annular groove phase mask N-band coronagraphic upgrade
Alyssa L. Miller, Jarron Leisenring, Michael Meyer +15
We describe the coronagraphic upgrade underway for the Mid-Infrared Array Camera-5 (MIRAC-5) to be used with the 6.5-m MMT telescope utilizing the new MMT Adaptive optics exoPlanet…
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 W. M. Keck Observatory infrared vortex coronagraph and a first image of HIP79124 B
Eugene Serabyn, Elsa Huby, Keith Matthews +22
An optical vortex coronagraph has been implemented within the NIRC2 camera on the Keck II telescope and used to carry out on-sky tests and observations. The development of this new…
A Mach-Zehnder interferometer based on orbital angular momentum for improved vortex coronagraph efficiency
P. Piron, C. Delacroix, E. Huby +5
The Annular Groove Phase Mask (AGPM) is a vectorial vortex phase mask. It acts as a half-wave plate with a radial fast axis orientation operating in the mid infrared domain. When p…
Annular Groove Phase Mask coronagraph in diamond for mid-IR wavelengths: manufacturing assessment and performance analysis
Christian Delacroix, Pontus Forsberg, Mikael Karlsson +7
Phase-mask coronagraphs are known to provide high contrast imaging capabilities while preserving a small inner working angle, which allows searching for exoplanets or circumstellar…
A diamond AGPM coronagraph for VISIR
Christian Delacroix, Oliver Absil, Dimitri Mawet +6
In recent years, phase mask coronagraphy has become increasingly efficient in imaging the close environment of stars, enabling the search for exoplanets and circumstellar disks. Co…
