A compact echelle spectrometer-spectrograph has been designed for use at the Cassegrain focus of the University of Wisconsin 91-cm telescope at Pine Bluff. Laboratory results obtained with this instrument show that it has great potential for both stellar and nebular studies. Typical photographs and photoelectric scans of laboratory spectra are shown. A method of determining the profile of the echelle blaze is discussed. The instrument has high dispersion, 2.5 A/mm at 5000 A with a camera focal length of 0.5 m, and a spectral purity of 1.25 A/mm of entrance slit.
一种紧凑型阶梯光栅光谱仪已被设计用于威斯康星大学位于派恩布拉夫的91厘米望远镜的卡塞格伦焦点处。用该仪器获得的实验室结果表明，它在恒星和星云研究方面都具有很大潜力。文中展示了实验室光谱的典型照片和光电扫描图。讨论了一种确定阶梯光栅闪耀轮廓的方法。该仪器具有高色散，在5000埃处为2.5埃/毫米，相机焦距为0.5米，入口狭缝的光谱纯度为1.25埃/毫米。
