In order to optimize the soft X-ray lens design, obtain high power density soft X-ray without other particles by combining it with plasma radiant point, experiments of measuring transmission efficiency with the power density range of 6×106~1.5×107 W/cm2 for the X-ray capillary on Qiangguang Ⅰ facility were carried out. The results show that, for the capillary of glass DM308, basically, the power density of the output soft X-ray from the capillary is linear with the power density of the incidence soft X-ray; when the power density of the incidence soft X-ray is 1.2×107 W/cm2, the average transmission efficiency is 16.3%. Based on the experiment results, soft X-ray lens were made, and power density 2.1×109 W/cm2 of soft X-ray without plasma fragment was obtained at the focal point.
