“…For the external slit (2.1 ), the spectral resolution is a factor of two lower (0.036 nm at 30.4 nm and 0.144 nm at 121.6 nm). The spatial resolution corresponds to 2 pixels (45 arcsec) for the slit closest to the disk (1.5 ), to 6 pixels ( 2 arcmin) for the intermediate slit (1.8 ) and to more than 8 pixels ( 3 arcmin) for the external slit (2.1 ) [7]. Taking into account that the detectors' pixels will be binned to match these spatial and spectral resolutions, the estimated countrates reported in Tables Table 5Table 6Table 7Table 8, meet the science requirements summarized in the Traceability Matrix (cfr.…”

“…The IEO consists of a single, small ( 40 mm) circular aperture. A small ( 71 mm) spherical mirror (M0) rejects back the disk-light through the IEO up to 1.1 (i.e., 1.17 R at 0.28 AU) [6], [7], [8].…”

METIS, the "Multi Element Telescope for Imaging and Spectroscopy", is a coronagraph selected by the European Space Agency to be part of the payload of the Solar Orbiter mission to be launched in 2017. The unique profile of this mission will allow 1) a close approach to the Sun (up to 0.28 A.U.) thus leading to a significant improvement in spatial resolution; 2) quasi co-rotation with the Sun, resulting in observations that nearly freeze for several days the large-scale outer corona in the plane of the sky and 3) unprecedented out-of-ecliptic view of the solar corona. This paper describes the experiment concept and the observational tools required to achieve the science drivers of METIS. METIS will be capable of obtaining for the first time:simultaneous imaging of the full corona in polarized visible-light (590-650 nm) and narrow-band ultraviolet HI Lyman ; monochromatic imaging of the full corona in the extreme ultraviolet He II Lyman spectrographic .These measurements will allow a complete characterization of the three most important plasma components of the corona and the solar wind, that is, electrons, hydrogen, and helium. This presentation gives an overview of the METIS imaging and spectroscopic observational capabilities to carry out such measurements.

“…1 shows a 3D sketch of the METIS coronagraph, with emphasis on the main optical elements described in this section. METIS is designed around an innovative concept for externally occulted solar coronagraph, based on an inverted external-occulter (IEO) [3,4]. The IEO is a small circular aperture which replaces the classical annular aperture of the standard externally occulted solar coronagraph design.…”
