This project will add a long-slit spectroscopic capability to an NSF supported infrared imaging system for the 1.8m Lowell Observatory telescope. The spectroscopic option will provide three complimentary capabilities: o A low resolution (lamda/delta lamda = 550) long slit (6.8') mode, which will disperse one of the J, H, or K atmospheric windows across the detector array in its entirety. o A cross-dispersed mode that allows observations at a resolution of 550 of the entire useful wavelength range from 1.18 to 2.45 (mu)m with a 30" long slit or from 0.96 to 2.45 (mu)m for a point source. o A higher resolution (lamda/delta lamda = 1500) mode with a more restricted slit length (2.6'); a positionable grating mount will allow the selection of wavelengths in this mode. All the options, including the changeover from imaging to spectroscopic observing, will be remotely controlled and rapidly selectable. There are two projects that the spectrometer will be directed towards: studies of the stellar content of galaxies and of the evolutionary status of young stellar objects. //

该项目将增加一个长缝光谱能力， NSF支持的1.8米Lowell红外成像系统 天文望远镜。 光谱选项将提供三个 补充功能： O 低分辨率（λ/Δ λ = 550）长狭缝（6.8“） 模式，这将分散J，H或K大气中的一个 整个探测器阵列上的窗口。 O 一种交叉分散模式，允许在 分辨率为550的整个有用波长范围， 1.18- 具有30”长狭缝的0.96至2.45（mu）m或 (mu)m对于点源。 O 更高分辨率（λ/Δ λ = 1500）模式， 狭缝长度更受限制（2.6 '）;可定位的光栅 安装将允许在此模式下选择波长。 所有选项，包括从成像到 光谱观测，将远程控制和迅速 可选的。 有两个项目，光谱仪将被引导 朝向： 研究星系中的恒星成分和 年轻恒星的演化状态 //
