Abstract

A unitary composite lens includes a body and an optical filter. The optical filter is embedded within the body.

Claims

1. A unitary composite lens comprising:

a body; and

an optical filter embedded within the body.

2. The unitary composite lens as claimed in claim 1, wherein the optical filter is formed integrally with the body.

3. The unitary composite lens as claimed in claim 1, wherein the optical filter comprises a substrate and a first filter film on the substrate.

4. The unitary composite lens as claimed in claim 3, wherein the optical filter further comprises a second filter film on an opposite surface of the substrate to the first filter film.

5. The unitary composite lens as claimed in claim 3, wherein the first filter film is an infrared cut filter.

6. The unitary composite lens as claimed in claim 4, wherein the second filter film is an infrared cut filter.

7. The unitary composite lens as claimed in claim 1, wherein the body is comprised of plastic material.

8. A lens module comprising:

a lens barrel; and

a unitary composite lens accommodated within the lens barrel, the unitary composite lens comprising a body and an optical filter embedded within the body.

9. The lens module as claimed in claim 8, wherein the optical filter is formed integrally with the body.

10. The lens module as claimed in claim 8, wherein the optical filter comprises a substrate and a first filter film on the substrate.

11. The lens module as claimed in claim 10, wherein the optical filter further comprises a second filter film on an opposite surface of the substrate to the first filter film.

12. The lens module as claimed in claim 10, wherein the first filter film is an infrared cut filter.

13. The lens module as claimed in claim 11, wherein the second filter film is an infrared cut filter.

14. The lens module as claimed in claim 8, wherein the body is comprised of plastic material.
