斯隆数字巡天五号（SDSS-V）是一个全天空光谱巡天，观测超过600万个天体，旨在解码银河系的历史，揭示恒星的内部运作，调查太阳系的起源，并跟踪宇宙中超大质量黑洞的生长。本地体积测绘仪（LVM）是一种设施，旨在提供一个连续的2500 deg 2积分场调查超过3.5年的时间从拉斯维加斯坎帕纳斯天文台（LCO）在智利。该设施包括四个小型（16厘米）望远镜，为三个由Winlight Systems设计和建造的台式多目标光谱仪提供科学，校准和分光光度学光。所有四个望远镜都将配备一个微透镜阵列积分场单元（IFU），将焦平面切割成35弧秒的大空间元素，同时保持光纤输入处的近远心耦合。科学IFU包括1801根光纤，另外143根光纤分配用于天空背景和分光光度校准，总计1944根光纤。每个光谱仪将由648根光纤馈电，这些光纤被重新格式化为线性阵列，形成入口狭缝。本文介绍了LVM-LCO光缆系统的光机设计。
The Sloan Digital Sky Survey V (SDSS-V) is an all-sky spectroscopic survey of >6 million objects, designed to decode the history of the Milky Way, reveal the inner workings of stars, investigate the origin of solar systems, and track the growth of supermassive black holes across the Universe. The Local Volume Mapper (LVM) is a facility designed to provide a contiguous 2500 deg2 integral-field survey over a 3.5 year period from Las Campanas Observatory (LCO) in Chile. The facility comprises four small (16 cm) telescopes that deliver science, calibration, and spectro-photometric light to three bench-mounted multi-object spectrographs, designed and build by Winlight Systems. All four telescopes will be equipped with a microlens array integral-field unit (IFU) to slice the focal plane into 35–arcsec large spatial elements while maintaining near-telecentric coupling at the fiber input. The science IFU comprises 1801 fibers, additional 143 fibers are allocated for sky-background and spectro-photometric calibration, totaling 1944 fibers. Each spectrograph will be fed by 648 fibers, which are reformatted into a linear array, forming the entrance slit. In this paper, we present the opto-mechanical design of the LVM-LCO fiber cable system.
