SPHERICAL MIRROR GRAZING INCIDENCE X-RAY OPTICS

摘要

AN OPTICAL SYSTEM FOR X-RAYS COMBINES AT LEAST TWO SPHERICAL OR NEAR SPHERICAL MIRRORS FOR EACH DIMENSION IN GRAZING INCIDENCE ORIENTATION TO PROVIDE THE FUNCTIONS OF A LENS IN THE X-RAY REGION. TO FOCUS X-RAY RADIATION IN BOTH THE X AND THE Y DIMENSIONS, ONE OF THE MIRRORS FOCUSSES THE X DIMENSION, A SECOND MIRROR FOCUSSES THE Y DIRECTION, A THIRD MIRROR CORRECTS THE X DIMENSION BY REMOVING COMATIC ABERRATION AND A FOURTH MIRROR CORRECTS THE Y DIMENSION. SPHERICAL ABERRATION MAY ALSO BE REMOVED FOR AN EVEN BETTER FOCUS. THE ORDER OF THE MIRRORS IS UNIMPORTANT.
