E-ELT INSTRUMENTATION - Phase A
In June 2007 ESO presented a plan for instrument and post-focal
adaptive optics studies to ESO Council. This plan identified six
instrument concepts which were to be studied in collaboration with
institutes in the ESO community, as well as two post-focal AO modules
(MCAO and LTAO), and two other instruments to be chosen after an open
call to the community for additional concepts. By early 2010 all
studies (see table below) had successfully been completed. In two
cases the consortia were led by ESO, two were set up by direct
negotiation with external institutes and all others were selected
after an open call for proposals.

Width of the field of view vs. wavelength coverage for the eight E-ELT proposed instruments currently under study. When the expected field of view is not squared, the average value of both dimensions or the diameter is shown. In the case of OPTIMOS and EAGLE (up) the shown value refers to the patrol field. For SIMPLE, the plot shows the slit length in single-object and long-slit modes. |
Pixel/spaxel size vs. wavelength coverage for the eight E-ELT proposed instruments currently under study. The diagonal black line shows the diffraction limit of the telescope as a function of wavelength. The values shown here refer to the sampling size of the instruments in their different observing modes. In the case of OPTIMOS-EVE(MOS), the quoted value corresponds to the fibre aperture. CODEX is only included for illustrative purposes as this instrument will not record any spatial information. |
Spectral resolution vs. wavelength coverage for the eight E-ELT proposed instruments currently under study. High, medium and low resolution channels are included when available. The arrow in SIMPLE indicates the potential upper limit to be reached depending on specific construction details. In the case of OPTIMOS-EVE(MOS) the arrow represents the range of resolution expected to be available. |
