Paper Abstract

This paper presents the Espresso Anamorphic pupil Slicer (APSU) implementation. For ESPRESSO that will be installed on ESO’s Very Large Telescope (VLT). In this work we will present the design and trade off for the pupil slicing system introduced in order to increase the resolving power, effectively decreasing slit width. It’s based onto simplified optical component that introduce large anamorphism while keeping low aberrations by means of cylindrical optics. We describe here the trade off between slicing through two adjacent squared doublets and two achromatic prisms. Preliminary integration and procurement is also discussed here.
