    Building on the remarkable achievements of Gaia in mapping the Milky Way in multiple dimensions, and in alignment with the ESA Voyage 2050 science programme, advancing galactic astrometry into the near-infrared has emerged as a promising direction for the fourth ESA large class mission. Achieving this goal will depend on significant progress in the development of the mission's detection chain,...

    CEA LETI develops second-generation cooled infrared focal plane array (FPA) technologies for high-performance imagers, targeting defense, Earth observation from space, and astronomy. Our technology covers the infrared spectrum from Short-Wave InfraRed (SWIR) to Very Long Wave InfraRed (VLWIR, 18µm cutoff). The entire process flow, from substrate and epilayer growth to Read-Out Integrated...

  4. 70. Ground Characterization of H2RG FPAs for the ARRAKIHS Mission at IFAE
    Jorge Jimenez
    11/03/2026, 16:45

    ARRAKIHS is an ESA fast mission selected in 2022 to analyze the nature of dark matter and galaxy formation through ultra-low surface brightness observations. Achieving the mission’s scientific goals requires stringent performance from the infrared focal plane. This work presents the current detector characterization activities for the ARRAKIHS mission, focused on the setups developed to...

  5. 50. Performance of Euclid H2RG detectors: IPC and persistance contributions
    Aurélia Secroun
    11/03/2026, 17:10

    Detector performance typically accounts for a significant part of an instrument’s overall performance, and thus has a major impact on mission success. For missions like Euclid, which demand exceptional precision and accuracy in flux measurements, it is essential to minimize and control detector systematics as rigorously as possible. To achieve this, pre-launch ground characterization enables...

  7. 72. Characterisation of H4RG-15 detectors for ground based astronomy in the era of ELTs
    Derek Ives
    11/03/2026, 18:00

    ESO has characterized upwards of 15 H4RG detectors with 15 µm pixels and 2.5 µm cut-off material. The ELT’s MICADO and HARMONI instruments require 17 of these detectors. We have constructed a purpose-built IR test facility, called FIAT, to allow full detector characterization. In the most recent period, we have now fully characterized 10 H4RG-15 detectors, for the MICADO instrument, in this...
