Abstract

The invention provides a method for preparing a super-resolution imaging lens with planar zooming magnification, comprising the following steps: preparing a circular or square or rectangular flat-bottom groove on a substrate; depositing a silver film layer on the substrate, then coating a cured sol layer on the silver film layer, wherein the sol layer can form an arc surface at the position of the groove under the action of surface tension, and the sol layer is cured after being heated or ultraviolet-irradiated; and so forth, depositing the silver film layers alternatively on the substrate, coating and curing the sol layers, obtaining a plurality of arc-surface film layers formed by a plurality of silver film layers and the sol layers in an alternative manner at the groove position till the groove is filled, and then obtaining the super-resolution imaging lens with planar zooming magnification, wherein an object plane and an image plane of the lens are planes respectively. The super-resolution imaging lens with planar zooming magnification can zoom or amplify images in a two-dimensional manner, and can be applied in super-resolution zooming of photoetching or amplification of images. Therefore, the difficulty that the existing super-resolution imaging lens with planar zooming magnification is difficult to manufacture is solved, and the application potential in the imaging and photoetching fields is large.
