Development of an adaptive optics testbed at MPIA for the ELT/Planetary Camera and Spectrograph (PCS)
Raphaël Pourcelot, Thomas Bertram, Peter Bizenberger +5
The Planetary Camera and Spectrograph (PCS) is a proposed second-generation instrument for the Extremely Large Telescope (ELT), dedicated to the direct imaging and characterization…
Maximising the mid-infrared high-contrast performance of ELT/METIS despite water vapour seeing
Olivier Absil, Gilles Orban de Xivry, Prashant Pathak +7
The Mid-infrared ELT Imager and Spectrograph (METIS) will be equipped with a SCAO system delivering Strehl ratios above 90% at L band (3.5 - 4.1 um) and close to 99% at N band (8 -…
Assembly, integration, and verification of MITESI: an optical testbed for simulating the ELT in the laboratory
Daniel J Ahrer, M. Concepción Cárdenas Vázquez, Thomas Bertram +5
MITESI is an optical testbed which simulates key characteristics of the ELT, ultimately producing an artificial natural guide star. It was designed primarily to enable testing of t…
A 5kHz modulator for pyramid wavefront sensors
Maximilian Häberle, Vianak Naranjo, Yared Reinarz +5
Despite the emergence of new types of wavefront sensors, the modulated pyramid wavefront sensor remains the workhorse for ELT instrumentation, and is among the options even for adv…
High strehl and high contrast for the ELT instrument METIS -- Final design, implementation, and predicted performance of the single-conjugate adaptive optics system
Markus Feldt, Thomas Bertram, Carlos Correia +8
The Mid-infrared ELT Imager and Spectrograph (METIS) is a first-generation instrument for the Extremely Large Telescope (ELT), Europe's next-generation 39 m ground-based telescope…
