This is a project to design and build a facility-class infrared cross-dispersed spectrograph instrument for the Infrared Telescope Facility which will provide a resolving power of up to 80,000 at 1.1 - 2.0 microns and 67,000 at 3 - 5 microns. The spectrograph is designed around a silicon immersion grating which not only reduces the size of the instrument but also permits high spectral resolution without requiring an extremely narrow slit. The use of the silicon immersion grating is important as this will be the first application on a 1-5 meter facility instrument and will therefore be an important demonstration of this technology for future instrumentation on the next generation of large telescopes. Observing time at the Infrared Telescope Facility is available to the general astronomical community so that this spectrograph will have a significant broader impact. The project will also train astronomy graduate students.

这是一个为红外望远镜设施设计和建造设施级红外交叉色散光谱仪的项目，该仪器将提供1.1 - 2.0微米分辨率高达80，000和3 - 5微米分辨率高达67，000的分辨率。光谱仪是围绕硅浸没光栅设计的，这不仅减小了仪器的尺寸，而且还允许高光谱分辨率，而不需要极窄的狭缝。 硅浸没光栅的使用很重要，因为这将是1-5米设施仪器上的首次应用，因此将是下一代大型望远镜未来仪器的重要示范。红外望远镜设施的观测时间可供一般天文学界使用，因此这台摄谱仪将产生更广泛的影响。 该项目还将培训天文学研究生。
