Investigation of aberrations of Kirkpatrick-Baez mirrors

The flux distributions in the focal plane of Kirkpatrick-Baez optics are investigated as the parameters of the focusing ellipse of the mirrors are changed from typical laboratory optics to synchrotron beam line optics. This work shows the effects of the most predominant focusing imperfections that arise from conditions that violate the original assumptions of Kirkpatrick-Baez systems, including orthogonality of the mirror surfaces and paraxial rays.
