Abstract

An imaging lens structure and method of imaging are presented. The imaging lens structure comprising a lens region defining an effective aperture of the lens structure. The lens region comprises an arrangement of lens zones distributed within the lens region and comprising zones of at least two different optical functions differently affecting light passing therethrough. The zones of at least two different optical functions are arranged in an interlaced fashion along said lens region corresponding to a surface relief of the lens region such that adjacent lens zones of different optical functions are spaced apart from one another along an optical axis of the lens structure a distance larger than a coherence length of light at least one spectral range for which said lens structure is designed.

Claims (29)

1. A spectacle lens comprising:

a first zone of the spectacle lens; and

a second zone of the spectacle lens;

wherein the second zone comprises a plurality of discrete lens segments of the spectacle lens interlaced with the first zone;

wherein the first zone is configured to apply a first refractive optical function to light passing therethrough and the plurality of discrete lens segments of the second zone are configured to apply a second refractive optical function to light passing therethrough, different to the first refractive optical function;

wherein the first refractive optical function comprises a first focal length and the second optical function comprises a second focal length, different to the first focal length;

wherein the first zone occupies a central portion of the lens that is devoid of the plurality of discrete lens segments of the second zone; and

wherein the plurality of discrete lens segments are distributed within a plurality of annular segments of the second zone of the spectacle lens about the central portion of the lens, each annular segment comprising a plurality of the discrete lens segments distributed within it about the central portion of the lens.

2. The spectacle lens of claim 1 , wherein the spacing between the plurality of discrete lens segments is a-periodic.

3. The spectacle lens of claim 1 , wherein the lens is non-diffractive by one or more of:

a) surface parts of the first zone and surface parts of the second zone are spaced-apart along the optical axis of the lens by more than a coherence length of visible light;

b) a physical dimension along the lens surface of both the first zone and interlaced second zone is greater than a maximal wavelength of visible light; and

c) the lens segments of the second zone are arranged in a disordered fashion.

4. The spectacle lens of claim 1 , wherein the lens is non-diffractive by two or more of:

a) surface parts of the first zone and surface parts of the second zone are spaced-apart along the optical axis of the lens by more than a coherence length of visible light;

b) a physical dimension along the lens surface of both the first zone and interlaced second zone is greater than a maximal wavelength of visible light; and

c) the lens segments of the second zone are arranged in a disordered fashion.

5. The spectacle lens of claim 1 , wherein surface parts of the first zone and surface parts of the second zone are spaced-apart along the optical axis of the lens by more than a coherence length of visible light.

6. The spectacle lens of claim 1 , wherein the lens segments of the second zone are arranged in a disordered fashion.

7. The spectacle lens of claim 1 , wherein the first zone is a base lens of the spectacle lens.

8. The spectacle lens of claim 7 , wherein the second zone is embedded in the base lens.

9. The spectacle lens of claim 8 , wherein the second zone is a surface relief etched in the base lens.

10. The spectacle lens of claim 1 , wherein the second zone forms part of a diffractive lens.

11. The spectacle lens of claim 1 , wherein the first zone and the second zone apply different phase coding to light passing through the spectacle lens.

12. The spectacle lens of claim 1 wherein the lens segments have the same dimensions and shapes.

13. The spectacle lens of claim 1 , wherein more of the light energy collected by the spectacle lens is collected by the first zone in comparison to the second zone.

14. The spectacle lens of claim 1 , wherein a fill factor of first zone to the second zone is between 50:50 and 70:30.

15. The spectacle lens of claim 1 , wherein surface parts of the first zone are spaced-apart along the optical axis of the lens from surface parts of the second zone by more than 0.5 micrometers.

16. The spectacle lens of claim 1 , wherein a physical dimension along the lens surface of both the first zone and interlaced second zone is greater than a maximal wavelength of visible light.
