GMT-Consortium大型地球探测仪(G-CLEF)是一种光纤馈电的光学梯形光谱仪，已被选为拉斯坎帕纳斯天文台目前正在建造的巨型麦哲伦望远镜(GMT)的第一台光仪器。我们设计的G-CLEF是一台通用的梯形光谱仪，其径向速度精度目标为0.1m/S，这将使它能够探测/测量一颗地球大小的行星在其宜居带围绕一颗太阳型恒星运行的质量。这一目标对仪器的所有方面都提出了挑战性的要求，其中一些最好直接纳入光学设计过程。在本文中，我们描述了G-CLEF仪器的初步光学设计，并简要描述了我们在非对称白色光瞳梯形结构中引入的一些新的解决方案。
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.
