XEUS使命的成功关键取决于在适合科学观测的轨道上部署一个10平方米级的望远镜系统。对于这样一个大型设施来说，最小化望远镜的质量和体积变得至关重要。我们描述了新的重量轻的光学器件的发展，使每单位面积的质量减少超过一个数量级，与传统的复制光学技术相比。有了如此大的收集面积，图像混淆限制也成为一个科学的驱动因素，要求弧秒级分辨率。我们描述的测量表明，分辨率的提高，提供了非常高的信心，这些要求可以得到满足。
The success of the XEUS mission depends critically on the deployment of a 10 square metre class telescope system in a suitable orbit for science observations. The minimisation of the telescope mass and volume becomes of critical importance for such a large facility. We describe developments of novel light weight optics that enable a reduction in mass per unit area of more than an order of magnitude, compared with traditional replication optics technology. With such a large collection area, image confusion limits become a scientific driver as well, demanding arcsecond class resolution. We describe measurements that demonstrate the improvement in resolution that gives very high confidence that these requirements can be met.
