Since refractive index of materials in the x-ray region is lower than 1  and x-ray is strongly absorbed by materials  it is very difficult to image objects in the x-ray region. Conventional imaging methods are hardly suitable to x-ray range. In general  grazing reflective imaging and coding aperture imaging methods have been adopted more and more. In this paper  according to user's requirement  we have designed a non-coaxial grazing KBA microscope. The microscope consists of two sets of perpendicular spherical mirrors  each set includes two parallel mirrors. Taking it as an example  we have compiled an optical computing program for the non-coaxial grazing imaging systems so as to analyze and evaluate aberrations of KBA microscope. Thus it can help us to get an optimal comprehension of KBA x-ray imaging system. In the same time  the analytical results provide reliable foundation for evaluating imaging quality of KBA microscope.
