NEID是用于WIYN望远镜的一种新型超精密多普勒谱仪。它是纤维馈送的，采用了经典的白色光瞳Echelle配置。在高分辨率模式下，NEID在天空中的光纤孔径仅为0.92“，其严格的径向速度误差预算导致了对光谱仪光学输入照明的非常严格的稳定性要求。因此，对光纤注入的要求是具有挑战性的。在本文中，我们描述了注入模块的布局和光学设计，包括一个宽带、高画质继电器和一个高性能的大气色散校正器(ADC)，带宽在380-930 nm。
NEID is a new extreme precision Doppler spectrometer for the WIYN telescope. It is fiber fed and employs a classical white pupil Echelle configuration. NEID has a fiber aperture of only 0.92” on sky in high-resolution mode, and its tight radial velocity error budget resulted in very stringent stability requirements for the input illumination of the spectrograph optics. Consequently, the demands on the fiber injection are challenging. In this paper, we describe the layout and optical design of the injection module, including a broadband, high image quality relay and a high-performance atmospheric dispersion corrector (ADC) across the bandwidth of 380 – 930 nm.
