The fabrication of high reflectivity multilayer minochromators usually involves depositing a greater number of bilayers than the calculated number for perfect multilayers. This deviation from ideal behavior occurs due to the presence of imperfections in layers. These imperfections are strongly dependent on the deposition process employed and the parameters during deposition. An understanding of the types of imperfections present may lead to attempts to minimize them. The imperfections should be taken into consideration for determining the sequence of d-spacing for making a supermirror.
