Abstract

We present the optical concept and design of a fiber-fed echelle spectrograph for precise radial velocity measurements in the near-infrared. The spectrograph is designed to achieve a nominal resolution λ/ Δλ of the order of 40000 and to cover the range from 0.9μm to 1.7μm in a single exposure. This spectrum is to be recorded on a 2048x2048 infrared detector. The instrument is designed to be mounted at 1 to 2 m class telescopes for survey purposes. We present in the optical design and the instrument capability. We do emphasis particularly on optical aberrations and thus discuss the instrument expected limitations from the optical viewpoint.
