The pinhole camera is an important device for inspecting of laser focal spot and target pointing in inertial confinement fusion experiments. In this paper, the Xray pinhole camera has been developed for ShengguangⅡup equipment. This study focuses on parameter and configuration optimization. And the devices have been designed, manufactured, assembled and tested. The results of test experiments show that the energy range is 1.05.5 keV, the spatial resolution is better than 20 μm, and the magnification ratio is 5.139.99. That proves that the pinhole camera can be applied on ShengguangⅡup equipment.
