Abstract
One of the most important requirements for soft x-ray optics is high normal incidence reflectivity. But to ensure a high throughput optical system, Schwarzchild objectives in particular, it is not only necessary to fabricate multilayer coatings with the highest possible reflectivity but to achieve the designed d-spacing uniformity/grading and match the d-spacings of the concave and convex mirrors. The latter is especially important for high throughput multi-mirror lithography optical schemes.[1]
