Abstract: Based on the urgent need of conducting imaging diagnostics of dense laser-produced plasma, we present the optical system design of Wolter type X-ray microscope based on Abbe's sine condition. This paper details the structural features and optical design approaches of Wolter microscope. The impacts of initial structure parameters including the object distance, magnification, grazing angle and mirror length of hyperbolic mirror on objective performance are studied quantitatively. According to ray-tracing simulation, the spatial resolution is better than 1 μm in a range of ±260 μm and better than 3 μm in a range of ±460 μm. The effective field of view is estimated as about 1 mm in diameter with a geometric solid angle of 6.1×10^-5 sr. The system is flat-response with an efficiency consistency of 93.7% over the field of view. This paper contributes to the development of high-resolution and high-flux hard X-ray imaging diagnostic instruments in the future.
