A versatile and efficient low- to moderate- resolution spectrograph for general use on the University of Hawaii's 2.2-m telescope on Mauna Kea will be constructed. While the spectrograph will be capable of carrying out a full range of conventional imaging and spectroscopic programs, special attention has been given to three specific areas important to users: (1) high-angular-resolution spectroscopy, (2) a spectral range from 3600 A to 2.3 um available in a single instrument, and (3) an easily accessible slit environment capable of taking a wide variety of slits, aperture plates, and image slicers. The instrument will be able to function in conjunction with a piezo- electrically-driven f/35 secondary currently being developed to provide fast guiding for high-resolution imaging and spectroscopy. The versatility of this instrument-particularly its abilities to switch between imaging and spectroscopic modes in a matter of seconds and to work over a wide spectral range- will make "block scheduling" of the telescope a more feasible option. The consequent reduction in frequency of instrument changes can be expected to improve the operation of the entire facility.

将建造一台多功能、高效的中低分辨率摄谱仪，供夏威夷大学莫纳克亚山 2.2 米望远镜通用。 虽然光谱仪能够执行全方位的常规成像和光谱程序，但特别关注对用户重要的三个特定领域：(1) 高角分辨率光谱，(2) 3600 光谱范围单个仪器可提供 1 至 2.3 um 的分辨率，以及 (3) 易于访问的狭缝环境，能够采用各种狭缝、孔径板和图像切片器。 该仪器将能够与目前正在开发的压电驱动的 f/35 次级光源结合使用，为高分辨率成像和光谱学提供快速引导。 该仪器的多功能性，特别是它能够在几秒钟内在成像和光谱模式之间切换以及在较宽的光谱范围内工作的能力，将使望远镜的“块调度”成为更可行的选择。 由此带来的仪器更换频率的减少有望改善整个设施的运行。
