Abstract
A meta lens assembly includes a first meta lens, a second meta lens arranged on an image side of the first meta lens, and a third meta lens arranged on an image side of the second meta lens, the first meta lens, the second meta lens, and the third meta lens being arranged from an object side of the meta lens assembly to an image side of the meta lens assembly facing an image sensor.
Claims24
A meta lens assembly comprising:
- a first meta lens;
- a second meta lens arranged on an image side of the first meta lens;
- and
- a third meta lens arranged on an image side of the second meta lens,
- wherein the first meta lens, the second meta lens, and the third meta lens are arranged from an object side of the meta lens assembly to an image side of the meta lens assembly facing an image sensor, and
- wherein an interval between the first meta lens and the second meta lens is less than or equal to about ⅕ of an interval between the second meta lens and the third meta lens, and
- wherein the second meta lens comprises a first region comprising first nano structures and a second region comprising second nano structures,
- wherein the first nano structures in the first region are arranged to gradually increase in size in a radial direction of the second meta lens, and
- wherein the second nano structures in the second region are arranged to gradually decrease in size in the radial direction of the second meta lens.
