Paper Abstract
The GMT-Consortium Large Earth Finder (G-CLEF) is a fiber fed, optical echelle spectrograph, which has been selected
as a first light instrument for the Giant Magellan Telescope (GMT) currently under construction at the Las Campanas
Observatory. We designed G-CLEF as a general-purpose echelle spectrograph with a precision radial velocity (PRV)
capability goal of 0.1 m/s, which will enable it to detect/measure the mass of an Earth-sized planet orbiting a Solar-type
star in its habitable zone. This goal imposes challenging requirements on all aspects of the instrument and some of those
are best incorporated directly into the optical design process. In this paper we describe the preliminary optical design of
the G-CLEF instrument and briefly describe some novel solutions we have introduced into the asymmetric white pupil
echelle configuration.
