针对X射线脉冲星导航与X射线空间通信的需求，对多层嵌套式X射线聚焦光学器件进行研制与实验标定。根据掠入射原理，对聚焦透镜进行理论设计，确定聚焦透镜的关键参数。讨论聚焦透镜的材料、镀膜等研制工艺。分别在可见光与X射线条件下测试了聚焦透镜的性能参数。结果表明测得可见光焦斑直径为14 mm，X射线焦斑直径为20 mm，在10 m真空管道中测得光子能量为1.5 keV时聚焦效率为30.2%，有效面积为2400 mm2。

Aiming at the demand on X-ray pulsar navigation and X-ray space communication, the multilayer nested X-ray focusing optical device is developed and tested. Theoretical design of focusing lenses is carried out according to the principle of grazing incidence, and key parameters of the focusing lenses are determined. The materials of focusing lenses and the preparation technologies such as the coating process are discussed. The performance parameters of the focusing lenses are tested respectively under the conditions of visible light and X-ray. The results show that the spot diameter of visible light is 14 mm, the spot diameter of X-ray is 20 mm, and the focusing efficiency is 30.2%. The effective area is 2400 mm2 in a 10 m vacuum pipe when the photon energy is 1.5 keV.
