  • Method and apparatus for producing a Fresnel zone plate
    Patent number: 9360603
    Abstract: A method of producing a Fresnel zone plate (15) comprising: making available a substrate (1, 4, 7) which is rotationally symmetrical with respect to its center axis (1a, 4a, 7a); applying layers (2a-d; 5a-d; 8a-d; 11) following in succession by means of an atomic layer deposition (ALD) method to faces (1b-c; 4b-c; 7b-c) of the substrate (1, 4, 7) without rotation of the substrate (1, 4, 7) in order to form a coated substrate, and severing (3a, b; 6a, b; 9a, b) at least one slice (13) from the coated substrate (1, 4, 7), by the coated substrate (1, 4, 7) being divided at least once at a right angle to the center axis (1a, 4a, 7a).
