 Ground-based instruments in the design phase

Instrumentation for ground-based observations has become a specialty for the Optics Department, occupying at any moment about half of the staff. Having significantly contributed to VLT instrumentation, we prepare the entry into the era of the ELTs, the Extremely Large Telescopes.



VLT-SPHERE

Search for and characterization of extra-solar planets by direct detection, based on Extreme Adaptive Optixs (XAO), stellar coronagraphy, and differential imaging. First light is foreseen in 2012. The Department is responsible for global system studies and for design, manufacture, and test of the main science module, IRDIS.

SUBARU-PFS

Multi-fiber spectrographe for a large cosmological survey. Light from 2400 fibres placed by a robot in the prime focus of the Japanese 8m SUBARU telescope is analysed by an assembly of 4 spectrographs, each of which has 3 channels, blue, red and NIR. The LAM ist responsable for design of the visible channels and AIT/AIV of the system.

EMIR

Multi-object spectrograph for the Gran Telescopio Canarias (GTC). The Department is responsible for the manufacture of gratings.

EAGLE

Multi-object integral field spectrograph with integrated adaptive optics (MOAO) for the ESO E-ELT. The Department provides project management for the French participation and contributes to optical design and alignment of the instrument.

OPTIMOS-DIORAMAS

Wide-field multi-object spectrograph for the ESO E-ELT. The Department provides global management of the project and participates to optical design and alignment of the instrument.

BIG BOSS

Fiber-based spectrographs for the 4m Kitt Peak telescope led by University of Berkeley. Coordination of the French participation and spectrograph optical design.
