我们描述了宇宙网成像仪（CWI），这是一种为帕洛玛天文台的海尔200英寸望远镜设计的紫外-可见积分场光谱仪。CWI是专门为观测废辐射而建造的。仪器视场为60“40”，光谱分辨率为R5000，空间分辨率有限。它利用体相位全息光栅，旨在覆盖光谱范围3800A至9500A，瞬时带宽为450A。CWI于2009年7月首次看到曙光，并于2010年5月进行了第一次成功的科学观测。
We describe the Cosmic Web Imager (CWI), a UV-VIS integral eld spectrograph designed for the Hale 200" telescope at the Palomar Observatory. CWI has been built specically for the observation of diuse radiation. The instrument eld of view is 60"40" with spectral resolving power of R5000 and seeing limited spatial resolution. It utilizes volume phase holographic gratings and is intended to cover the spectral range 3800A to 9500A with an instantaneous bandwidth of 450A. CWI saw rst light in July 2009, and conducted its rst successful scientic observations in May 2010.
