X * ray microscopy is an invaluable imaging method in many research areas with applications at physical, medical and biological problems as well as material science. Especially XUV / soft X-ray microscopy offers the great potential for investigating sensitive biological samples in their natural environment with low dose to reduce radiation damage and high spatial and energy resolution to address questions concerning sub cellular features or elemental composition. Here we report on our concept of an ultra compact microscope utilizing laser driven high harmonic radiation with ~ 73 eV energy as a light source and a dedicated zone plate operated in transmission as the main focussing element combined with different detectors which enables us to run this system in scanning mode as a STXM but also in a modified version as a high resolution instrument in diffraction mode employing the CDI technique. Furthermore due to our pulsed light source the possibility of time-resolved microscopic analysis is given with a possible few-femtosecond temporal resolution.
