Mechanical design of NESSI: New Mexico Tech extrasolar spectroscopic survey instrument

摘要

NESSI: the New Mexico Tech Extrasolar Spectroscopic Survey Instrument is a ground-based multi-objectspectrograph that operates in the near-infrared. It will be installed on one of the Nasmyth ports of theMagdalena Ridge Observatory (MRO) 2.4-meter Telescope. NESSI operates stationary to the telescopefork so as not to produce differential flexure between internal opto-mechanical components during orbetween observations. In this paper we report on NESSI's detailed mechanical and opto-mechanical design,and the planning for mechanical construction, assembly, integration and verification.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
