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.

夏威夷大学在莫纳克亚山的2.2米望远镜上将建造一个通用的、高效的低到中等分辨率光谱仪。虽然光谱仪将能够执行全范围的常规成像和光谱程序，但特别注意对用户重要的三个特定领域：(1)高角分辨率光谱学，(2)单个仪器的光谱范围从3600 a到2.3 um，以及(3)易于接近的狭缝环境，能够拍摄各种狭缝，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f/35辅助系统一起工作，为高分辨率成像和光谱提供快速指导。这台仪器的多功能性——尤其是它在几秒钟内就能在成像和光谱模式之间切换的能力，以及在很宽的光谱范围内工作的能力——将使望远镜的“块调度”成为一个更可行的选择。因此，仪器更换频率的降低有望改善整个设施的运行。
