【 摘 要 】
For point projection and phase contrast imaging very small x-ray spot sizes are the key to achieve high resolution images. This article shows a concept of demagnifing the spot of an 8-keV micro focus x-ray tube with a zoneplate. The zoneplate in combination with an order selection aperture acts as a monochromator, which is an enhancement especially for phase contrast imaging. With this concept, the resolution in our point projection microscope has been improved by a factor about two.
