The mask-back exposure technique is introduced to fabricate the lenses. The focusing performance of this device is tested at Beijing Synchrotron Radiation Facility (BSRF). At the distance of 1.65m from the lenses  an obviously focusing performance in one dimension is observed. The relative intensity of the lenses with the largest gain is about 217.7  the gain of the lens is about 1.15  and the dimension of the focus is about 33m. The focusing performance of this device can be improved through the developing of the mask-back exposure technique. 2009 Trans Tech Publications  Switzerland.   The three-dimensional focusing behaviors of the compound x-ray lenses (EI CONFERENCE) 会议论文  OAI收割 Optical Design and Testing II, November 8, 2004 - November 11, 2004, Beijing, United states Le Z.; Liu K.; Liang J.; Zhang M.; Quan B. 收藏  |  浏览/下载：16/0  |  提交时间：2013/03/25 A theoretical method for evaluating the three-dimensional focusing performances of the compound x-rays lenses is presented in the present paper. The relationship between the transverse and axial focusing behaviors is considered and a simple calculation that predicts the transverse and axial focusing behaviors of the compound x-ray lenses is also presented. As an example  the three-dimensional focusing performance of a compound x-ray lens with Al material is predicted. The dependences of the three-dimensional focusing performances on the compound lenses' structural parameters are observed for the Al compound x-ray lens. Moreover  the approximate tolerances in the setting of the receiving planes are also considered for x-rays of 4.95keV  14.99keV and 29.78keV.
