加拿大天文研究所（IAC）正在为位于losmuchachos天文台的4.2米威廉赫歇尔望远镜的卡塞格伦焦点设计和建造一个普通用户近红外光谱仪（LIRIS）。LIRIS将是一个近红外中分辨率光谱仪，设计用于在1000到5000之间的光谱分辨率范围内工作，并具有日冕、多项目和偏振观测的附加功能。由于使用了罗克韦尔制造的新型1024 X 1024像素HgCdTe夏威夷探测器，该仪器可以将足够的空间分辨率与大范围的有用视场相结合。位于低温恒温器内的所有光学器件和机构将被冷却到100 K以下。探测器将在77k的温度下工作。校准和跟踪将使用现有的卡塞格伦A和G盒进行，其中将纳入近红外校准系统。
The Instituto de Astrofisica de Canarias (IAC) is undertaking the design and construction of a common-user near IR spectrograph (LIRIS) for the Cassegrain focus of the 4.2 m William Herschel Telescope sited at the Observatorio del Roque de Los Muchachos. LIRIS will be a near IR intermediate-resolution spectrograph designed to operate over a spectral resolution range between 1000 and 5000, with added capabilities for coronographic, multiproject and polarimetric observations. The instrument allows the combination of an adequate spatial resolution with a large useful field of view across the slit, thanks to the use of the new 1024 X 1024 pixel HgCdTe Hawaii detector manufactured by Rockwell. All the optics and mechanisms situated inside the cryostat will be cooled to below 100 K. The detector will operate at 77 K. Calibration and tracking will be made with the existing Cassegrain A and G Box, into which a near IR calibration system will be incorporated.
