The design and performance of an Aerobee 150 rocket-borne solar spectrograph covering a wavelength range of 10-385 A are discussed. The spectrograph uses a gold-coated replica concave grating of 3-m radius with 1200 grooves/mm at an angle of incidence of 88 degrees . The spectra are recorded on glass photographic plates making possible wavelength determination to 0.003 A if known standard wavelengths occur frequently enough. Special attention to scattered light made possible the photographing of the solar spectrum from 60 A to 385 A without using filters to absorb the strong visible and uv sunlight, although the solar spectrum was also recorded through metal foil filters. In the laboratory the spectrograph has been used to record spectra of highly ionized metals with a resolution of 0.03 A or better.
讨论了一种覆盖10 - 385埃波长范围的Aerobee 150火箭搭载太阳摄谱仪的设计与性能。该摄谱仪使用半径为3米、每毫米1200条刻线的镀金复制凹面光栅，入射角为88度。光谱记录在玻璃照相底片上，如果已知标准波长出现的频率足够高，波长测定精度可达0.003埃。对散射光的特别关注使得在不使用滤光片吸收强烈的可见光和紫外太阳光的情况下，能够拍摄60埃至385埃的太阳光谱，不过太阳光谱也通过金属箔滤光片进行了记录。在实验室中，该摄谱仪已用于记录高电离金属的光谱，分辨率可达0.03埃或更高。
