Experimental results for image quality and scatter in far-UV light are used to choose between the conventionally polished Solar Extreme-Ultraviolet Rocket Telescope and Spectrograph (SERTS-A) and computer-controlled polished SERTS-C Wolter type II solar rocket telescopes for an extreme-UV flight instrument. In 124-nm light the SERTS-C telescope image had a 0.67-arcsec full width at half-maximum (FWHM), compared with a 1.25-arcsec FWHM for the SERTS-A telescope. In addition SERTS-C had twice the peak irradiance of SERTS-A and an order of magnitude lower near-angle scatter. The inflight performance of the telescopes is consistent with laboratory findings.
利用远紫外光下图像质量和散射的实验结果，在传统抛光的太阳极紫外火箭望远镜和摄谱仪（SERTS - A）以及计算机控制抛光的SERTS - C沃尔特II型太阳火箭望远镜之间进行选择，以用于极紫外飞行仪器。在124纳米的光线下，SERTS - C望远镜图像的半高全宽（FWHM）为0.67角秒，而SERTS - A望远镜的半高全宽为1.25角秒。此外，SERTS - C的峰值辐照度是SERTS - A的两倍，近角散射低一个数量级。望远镜的飞行性能与实验室结果一致。
