read moreMetalens is a lens with the ability to focus and capture light signals beyond the diffraction limit. The basic principle is to change the curvature of the lens to achieve the focusing or dispersion of light, via the use of man-made sub-wavelength unit structure in the traditional medium for wavefron
read moreMetalenses are very suitable for laser processing, as they provide a long depth of focus and can easily and accurately mark and process various non planar objects.

read moreLithography is the transfer of a designed pattern onto a flat surface, either directly or via an intermediate medium - excluding areas of the surface where the pattern is not required. In photomask lithography, where a design is patterned onto a substrate, a laser is used to expose the pattern, allowing deposited material to be etched away, preparing it for further processing. This lithography met
