Abstract

In this presentation, we detail the optical fiber-feed system for the new ultra-precise radial velocity spectrometer – NEID, which is an ultrastable instrument spanning a wavelength range of 380 to 930 nm. We discuss the various subsystems of the optical fiber-feed, including the process of design, assembly and testing of each component to ensure that it meets the strict requirements to achieve the instrumental precision goal for NEID.
