A 6.65-m normal incidence vacuum spectrograph has been provided with a photoelectric scanner that is easily interchangeable with the original plate holder. The scanner consists essentially of a photoelectric detector and an exit slit that scans mechanically along the focal surface while the grating and entrance slit remain stationary. The design and construction of the 6.65-m scanning spectrometer, which operates in the 120-300-nm wavelength region, are discussed. The wavelength resolution of 0.001 nm obtained photoelectrically is better than that of any existing vacuum monochromator. The performance of the instrument is illustrated with vacuum ultraviolet scans of the (1, 5) band of the Fourth Positive system of CO in emission, and the (14, 0) band of the Schumann-Runge system of O(2) in absorption.
一台6.65米垂直入射真空光谱仪配备了一台光电扫描仪，它可轻松与原来的底片暗盒互换。该扫描仪主要由一个光电探测器和一个出射狭缝组成，当光栅和入射狭缝保持固定时，出射狭缝沿焦面进行机械扫描。本文讨论了工作在120 - 300纳米波长区域的6.65米扫描光谱仪的设计与构造。通过光电方式获得的0.001纳米波长分辨率优于任何现有的真空单色仪。用一氧化碳第四正系统（1, 5）带发射的真空紫外扫描以及氧分子舒曼 - 伦格系统（14, 0）带吸收的真空紫外扫描展示了该仪器的性能。
