爱因斯坦天文台的反射镜代表了X射线光学技术的重大进步，并且比之前的望远镜经过了更全面的测试。其成像具有一个狭窄的、与波长无关的核心，以及较宽的与能量相关的侧翼。核心的宽度与在制造和组装过程中进行的机械和可见光测量所预期的大致相同。响应函数的侧翼是由微观表面散射引起的，但对这一过程仅有定性的了解。改善表面纹理以减少广角散射是大型X射线光学器件发展中最紧迫的任务。这些反射镜经受住了实验集成阶段和发射过程，并且在轨道上的性能与在地面上时相同。©（1979年）版权归SPIE——国际光学工程学会所有。仅允许个人使用时下载摘要。
The mirrors for the Einstein Observatory represent a substantial advance in the state of the art x-ray optics, and have been tested more thoroughly than previous telescopes. The image is characterized by a narrow, wavelength independent core, and broad energy dependent wings. The width of the core is about that expected from mechanical and visible light measurements taken during fabrication and assembly. The wings of the response function are caused by microscopic surface scattering, but only a qualitative understanding of this process exists. Improvement in surface texture to reduce the wide angle scatter is the most urgent task in the development of large x-ray optics. The mirrors have survived the experiment integration period and launch, and are performing in orbit as they performed upon the ground.© (1979) COPYRIGHT SPIE--The International Society for Optical Engineering.
