The extreme ultraviolet, double-dispersion, photographic spectrograph, Apollo Telescope Mount (ATM) Experiment S082B on Skylab is described. Novel features were the use of a predisperser grating with a ruling whose spacing varied approximately linearly with distance for the purpose of increasing the instrument speed by reducing the astigmatism and a photoelectric servo-system to stabilize to 1 sec of arc the solar image at various near-limb positions. The 970-3940-A range was covered in two sections with effective lambda/Deltalambda congruent with 30,000 from 1100 A to 1970 A. The spatial resolution was 2 x 60 solar sec of arc. During the Skylab mission 6400 exposures were made with the instrument pointed by an astronaut at selected and recorded'solar positions.
本文描述了在天空实验室上的极端紫外双色散照相光谱仪，即阿波罗望远镜支架（ATM）实验S082B。其新颖之处在于使用了一种预色散光栅，该光栅的刻线间距随距离近似线性变化，目的是通过减少像散来提高仪器速度，以及采用了一个光电伺服系统，以便在太阳边缘附近的不同位置将太阳图像稳定到1角秒。970 - 3940埃的波段分两部分覆盖，在1100埃至1970埃范围内有效色散率λ/Δλ约为30000。空间分辨率为2×60太阳角秒。在天空实验室任务期间，宇航员将该仪器指向选定的太阳位置并进行记录，共拍摄了6400张照片。
