Summary: | The invention is suitable for the technical field of curved-surface bent crystal preparation, and provides a curved-surface bent crystal preparation method, which comprises the following steps: providing a female die and a wafer to be processed, the female die having a first curved surface matched with the curved surface of a target curved-surface bent crystal; curved surface parameters of the target curved surface bent crystal are obtained, wherein the curved surface parameters comprise the curved surface radius and the curved surface radian; applying first pressure to two first edges, extending along the first direction, of the wafer, so that the first edges are attached to the first curved surface until the first edges form a curved surface structure matched with the shape of a corresponding area in the first curved surface; a plurality of contact points distributed along the meridian direction are arranged between the first pressure and the wafer, and the first direction is a direction corresponding to th |
