Abstract
The new transmission X-ray microscope (TXM) at BESSY II is the first X-ray microscope working with a rotating condenser-monochromator (RK) for the object illumination [1]. This condenser concept uses a linear monochromator with an off-axis transmission zone plate (OTZ) followed by a pair of rotating mirrors. Details of the design and characteristics are shown.
