Abstract
To achieve very-high spectral resolutions (R>100,000) with large telescopes (D>8m) new optical solutions have been investigated in the context of the ESPRESSO project for the VLT, starting from the initial design of CODEX for the E-ELT. ESPRESSO is a high-efficiency, high-stability, high-resolution visible spectrograph for the combined Coude focus of the VLT. Among these new solutions, we can mention: free-form optics, used to design an all-mirror anamorphic pupil slicer, large mosaic echelle grating, slanted VPH gratings, super-corrected atmospheric dispersion corrector. All these solutions have been usefully applied to design the spectrograph for ESPRESSO, and its Coude relay system.
