Collaborative Research: Magellan II Echellette Spectrograph

红外梯队光谱仪将由麦哲伦财团的研究人员设计、制造、组装和测试，用于麦哲伦II号望远镜。它将能够在保持高分辨率和可见光谱全波长覆盖的情况下，观测紫外（向蓝3600埃）波长区域内的微弱目标。该设计结合了一个中阶反射衍射光栅与一个大的熔融硅棱镜，以提供交叉色散。一个140毫米焦距的施密特相机将聚焦100毫米的准直光束到一个低噪声；背光CCD优化紫外覆盖。＊＊＊

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. ***
