An echelle grating spectrograph is ideal for use in a rocket when high resolution is required becaus itoccupies a minimum of space. The instrument described covers the range 4000-2000 A with a resolution of 0.03 A. It was designed to fit into the solar biaxial pointing-control section of an Aerobee-150 rocket. The characteristics of the spectrograph are illustrated with laboratory spectra of iron and carbon are sources and with solar spectra obtained during rocket flights in 1961 and 1964. Problems encountered in analyzing the spectra are discussed. The most difficult design problem was the elimination of stray light when used with the sun. Of the several methods investigated, the most effective was a predispersing system in the form of a zero-dispersion double monochromator. This was made compact by folding the beam four times.
当需要高分辨率时，阶梯光栅摄谱仪是火箭上使用的理想仪器，因为它占用空间最小。所描述的仪器覆盖4000 - 2000埃的范围，分辨率为0.03埃。它被设计成适合于Aerobee - 150火箭的太阳双轴指向控制部分。用铁和碳弧光源的实验室光谱以及1961年和1964年火箭飞行期间获得的太阳光谱说明了摄谱仪的特性。讨论了分析光谱时遇到的问题。最困难的设计问题是与太阳一起使用时消除杂散光。在研究的几种方法中，最有效的是零色散双单色仪形式的预色散系统。通过将光束折叠四次使其紧凑。
