AST-0215989Thompson, Ian B.An infrared echelle spectrograph will be designed, fabricated, assembled and tested for use at the Magellan II telescope by researchers associated with the Magellan consortium. It will be capable of observing faint targets in the wavelength region in the UV (blueward of 3600 Angstroms), while maintaining high resolution and full wavelength coverage of the visible spectrum. The design incorporates a medium order reflection diffraction grating in combination with a large fused-silica prism to provide cross dispersion. A Schmidt camera with 140-mm focal length will focus the 100 mm collimated beam onto a low noise; back illuminated CCD optimized for UV coverage. ***

一台红外梯形光谱仪将由与麦哲伦联盟有关的研究人员设计、制造、组装和测试，以供麦哲伦II望远镜使用。它将能够在紫外光(3600埃蓝风)的波长区域观察微弱目标，同时保持高分辨率和可见光光谱的全波长覆盖。该设计结合了一个中阶反射衍射光栅和一个大的熔融硅棱镜来提供交叉色散。一台140 mm焦距的施密特相机将把100 mm的准直光束聚焦到低噪声上；背照式CCD优化了紫外线覆盖范围。***
