Classification: CPC G | IPC G

Claim 0:
1. A lens assembly comprising:
a first lens having positive optical power with respect to incident light incident from an object side and having a convex surface facing the object side; and
a second lens comprising a meta-lens having negative chromatic aberration with respect to the incident light passing through the first lens.
wherein the meta-lens satisfies the following equation:

fM1λ1=fM2λ2=fM3λ3,

where fM1 is a focal length of the meta-lens for light of a first wavelength λ1 of the incident light, fM2 is a focal length of the meta-lens for light of a second wavelength λ2 of the incident light, and fM3 is a focal length of the meta-lens for light of a third wavelength λ3 of the incident light.
