Abstract
Some embodiments of the technology disclosed herein relate to a lens assembly including a lens base and a lens fill. The less base is constructed of a first material and defines a lens interior surface and a plurality of ribs extending axially from the lens interior surface. The plurality of ribs define a plurality of cavities between the plurality of ribs. The lens fill is constructed of a second material and is located within the plurality of cavities. The first material includes a plastic and the second material includes a plastic.
Claims19
A lens assembly comprising:
- a lens base constructed of a first material, wherein the lens base defines a lens interior surface and a plurality of ribs extending axially from the lens interior surface, wherein the plurality of ribs define a plurality of cavities between the plurality of ribs, wherein the lens base comprises a convex lens and a flange extending laterally from the convex lens, wherein the convex lens is configured to transmit less than or equal to 120 GHz electromagnetic waves;
- and
- a lens fill constructed of a second material, wherein the lens fill is located within the plurality of cavities,
- wherein the first material comprises a plastic and the second material comprises a plastic.
A method of making a lens comprising:
- molding a lens base having a lens interior surface and a plurality of ribs extending axially from the lens interior surface using a first material, wherein the plurality of ribs define a plurality of cavities between the plurality of ribs, wherein molding the lens base comprises molding a convex lens and a flange extending laterally from the convex lens, wherein the lens is configured to transmit less than or equal to 120 GHz electromagnetic waves;
- and
- molding a lens fill within the plurality of cavities using a second material.
A radar lens system comprising:
- a lens base constructed of a first material, wherein the lens base comprises a convex lens and a flange extending laterally from the convex lens, wherein the convex lens defines a lens interior surface and a plurality of ribs extending axially from the lens interior surface, and wherein the plurality of ribs define a plurality of cavities between the plurality of ribs;
- and
- a lens fill constructed of a second material, wherein the lens fill is located within the plurality of cavities, and,
- wherein the flange defines at least one window and the lens fill extends across the at least one window.
