  • Zone compensated multilayer laue lens and apparatus and method of fabricating the same
    Patent number: 9082522
    Abstract: A multilayer Laue Lens includes a compensation layer formed in between a first multilayer section and a second multilayer section. Each of the first and second multilayer sections includes a plurality of alternating layers made of a pair of different materials. Also, the thickness of layers of the first multilayer section is monotonically increased so that a layer adjacent the substrate has a minimum thickness, and the thickness of layers of the second multilayer section is monotonically decreased so that a layer adjacent the compensation layer has a maximum thickness. In particular, the compensation layer of the multilayer Laue lens has an in-plane thickness gradient laterally offset by 90° as compared to other layers in the first and second multilayer sections, thereby eliminating the strict requirement of the placement error.
    Type: Grant
