Descripción
HARMONI is a visible and near-infrared (0.47 to 2.45 μm) integral
field spectrometer, providing the E-ELT's core spectroscopic capability,
over a range of resolving powers from R
(≡λ/Δλ)~500 to R~20000. The instrument
provides simultaneous spectra of ~32000 spaxels at visible and near-IR
wavelengths, arranged in a √2:1 aspect ratio contiguous field.
HARMONI is conceived as a workhorse instrument, addressing many of the
E-ELT's key science cases, and will exploit the E-ELT's scientific
potential in its early years, starting at first light. HARMONI provides
a range of spatial pixel (spaxel) scales and spectral resolving powers,
which permit the user to optimally configure the instrument for a wide
range of science programs; from ultra-sensitive to diffraction limited,
spatially resolved, physical (via morphology), chemical (via abundances
and line ratios) and kinematic (via line-of-sight velocities) studies of
astrophysical sources. Recently, the HARMONI design has undergone
substantial changes due to significant modifications to the interface
with the telescope and the architecture of the E-ELT Nasmyth platform.
We present an overview of the capabilities of HARMONI, and of its design
from a functional and performance viewpoint.
