Description
The European Solar Telescope (EST) is a 4-m class solar telescope to be
located in the Canary Islands which is currently in its conceptual
design study. EST is a pan-european project (with 29 partners, plus 7
collaborating institutions, from 14 countries) promoted by the European
Association for Solar Telescopes (EAST). In the current concept, the
main telescope and its transfer optics assemblies 14 mirrors to provide
a Science Coudé Focus with an F/50 telecentric beam. It is
diffraction-limited in a FOV of 1 arcmin with an unvignetted FOV of
2'x2'. The whole system is being optimized in throughput for several
instruments observing simultaneously in a spectral range from 0.39 μm
to 2.3 μm. Its innovative concept integrates an optical transfer
stage assembling multiconjugated adaptive optics with optical field
de-rotation and with a perfect balance of the whole system in terms of
polarization being also time and wavelength invariant.
