Abstract: Provided is an athermal metalens, the metalens includes: a substrate and a plurality of nanostructures; the plurality of nanostructures are set on at least one side of the substrate, and are arranged in a periodicity; where a thermal refractive index coefficient of the plurality of nanostructures is less than a reference thermal refractive index coefficient; or each nanostructure is composed of at least two materials, and the product of the thermal refractive index coefficient of the at least two materials is less than 0. Thus, the effective refractive index of the nanostructures is insensitive to the temperature changes, and the reduced imaging performance of the metalens caused by temperature drift is improved.
