AbstractNEID is a high resolution echelle spectrograph designed to enable extremely precise Doppler radial velocity observations of stars in the 380-930nm wavelength range1. It has recently been installed at the 3.5m WIYN telescope at Kitt Peak National Observatory, and is currently being commissioned. The design is based on a white pupil layout with a monolithic parabolic primary mirror and a 195mm pupil size on the R4 Echelle grating. Here we describe the optical and mechanical design, assembly, and alignment of the fiber injection system which converts the native focal ratio of the sky, calibration, and science fibers to the focal ratio required to form the 195mm collimated beam. © 2020 SPIE
