传统理论中采用的近似方法所产生的理论面形误差是弯镜纳米聚焦的主要障碍之一。讨论了近似和解析修正的影响，并在没有任何近似的精确数学分析中描述了椭圆弯曲镜理论。这些近似对于掠射角较大、镜长较大、数值孔径较大的聚焦系统是有害的。本文描述和讨论了等矩和单矩弯曲镜的特性。单力矩弯曲镜由于其明显的优点，在纳米聚焦方面具有很大的潜力。
One of the main hurdles for nanometer focusing by a bending mirror lies in the theoretical surface errors by its approximations used for the traditional theory. The impacts of approximations and analytical corrections have been discussed, and the elliptically bent mirror theory has been described during exact mathematical analysis without any approximations. These approximations are harmful for the focusing system with bigger grazing angle, bigger mirror length, and bigger numerical aperture. The properties of equal-moment and single-moment bent mirrors have been described and discussed. Because of its obvious advantages, a single-moment bending mirror has high potential ability for nanometer focusing.
