Paper Abstract

One of the highest scientific priorities for the E-ELT is to characterise exoplanets and to image Earth-like planets with the dedicated planetary camera and spectrograph, ELT-PCS. Detailed design and construction of ELT-PCS requires R and D to be undertaken for specific components. In this paper we discuss plans to progress this R and D for the integral field spectrograph technology, with the aim of determining the best contrast achievable with both a lenslet and a slicer based spectrograph. In particular, we present the preliminary design for a new bench spectrograph capable of accepting either of the two competing technologies as its input.
