## Abstract

A split lens includes a first lens group including a first set of lenses, a second lens group including a second set of lenses, and at least one light shielding element. The light shielding element is disposed between the lens at the bottom position of the first lens group and the lens at the top position of the second lens group, such that a predetermined light path is formed between the first lens group and the second lens group, thereby conforming to the structure of the split lens.

## Claims

### Claim at position 1

1: A split lens, comprising:
at least a first lens group comprising at least a first lens set and a first lens barrel, wherein said first lens set is mounted in said first lens barrel;
at least a second lens group comprising at least a second lens set and a second lens barrel, wherein said second lens set is mounted in said second lens barrel; and
wherein the first lens barrel is configured to fit into said second retention portion of said second lens barrel, and the first lens barrel and the second lens barrel are fixed together.

### Claim at position 2 (depends on 1)

2: The split lens, as recited in claim 1, further comprising:
at least a light shielding element disposed between said first lens set and said second lens set to form a predetermined light path between said first lens group and said second lens group.

### Claim at position 3 (depends on 1)

3: The split lens, as recited in claim 1, wherein said first lens barrel further comprises a first retention portion formed at the outer side of the bottom end portion of said first lens barrel, and said second lens barrel further comprises a second retention portion formed at the inner side of the top end portion of said second lens barrel, wherein said first retention portion and said second retention portion are connected with each other, such that said first lens barrel and said second lens barrel are fixed to form an integrated lens configuration.

### Claim at position 4 (depends on 2)

4: The split lens, as recited in claim 2, wherein a diameter of said bottom end portion of said first lens barrel is smaller than a diameter of said top end portion of said second lens barrel, such that said first retention portion of said first lens barrel is configured to fit into said second retention portion of said second lens barrel so as to fix said first lens barrel and said second lens barrel.

### Claim at position 5 (depends on 3)

5: The split lens, as recited in claim 3, further comprising a connecting element, wherein said first retention portion of said first lens barrel is adhered with said second retention portion of said second lens barrel by said connecting element.

### Claim at position 6 (depends on 3)

6: The split lens, as recited in claim 3, further comprising a connecting element, wherein said second lens barrel further has a retention groove formed at a top side of said second lens barrel corresponding to said first retention portion of said first lens barrel, wherein said connecting element is filled in said retention groove to couple said first retention portion and said second retention portion with each other.

### Claim at position 7 (depends on 3)

7: The split lens, as recited in claim 3, wherein the first retention portion defines a first inner retention surface and a first outer retention surface, and the second retention portion defines a second outer retention surface, and the first outer retention surface is located at a lower edge of the first lens barrel, and the second outer retention surface is located at an upper edge of the second lens barrel.

### Claim at position 8 (depends on 7)

8: The split lens, as recited in claim 7, wherein the first outer retention surface of said first retention portion is adhesively affixed to a top side of said second retention portion.

### Claim at position 9 (depends on 3)

9: The split lens, as recited in claim 3, wherein said first retention portion is protruded from an outer lateral side of said first lens barrel, wherein said first retention portion and said second retention portion are connected with each other at a position that said bottom end portion of said first lens barrel is extended into said second retention portion for connecting said first lens barrel and said second lens barrel with each other.

### Claim at position 10 (depends on 9)

10: The split lens, as recited in claim 9, wherein said bottom side of said first retention portion is bonded to a top lateral side of said second retention portion by adhesive.

### Claim at position 11 (depends on 9)

11: The split lens, as recited in claim 9, wherein said retention groove is formed at said top side of said second retention portion for accommodating at least one connecting element to bond said second retention portion with said first retention portion.

### Claim at position 12 (depends on 2)

12: The split lens, as recited in claim 2, wherein said second lens set comprises two or more lens, and one of said light shielding elements is disposed on a top surface of said lens at an upper position of said second lens set.

### Claim at position 13 (depends on 12)

13: The split lens, as recited in claim 12, wherein said first lens set comprises two or more lens, and said light shielding elements are disposed at bottom surfaces of said lens in said first lens set and top surfaces of said lens in said second lens set respectively.

### Claim at position 14 (depends on 2)

14: The split lens, as recited in claim 2, wherein at least one of said light shielding elements is disposed between two adjacent lenses which are located at said first lens group and said second lens group respectively.

### Claim at position 15 (depends on 14)

15: The split lens, as recited in claim 14, wherein said two adjacent lenses are configured as an upper lens and a bottom lens respectively, wherein said light shielding element is disposed on a bottom surface of said upper lens or a top surface of said bottom lens.

### Claim at position 16 (depends on 1)

16: The split lens, as recited in claim 1, further comprising at least one spacing element disposed between two lenses of at least one of said first lens set and said second lens set.

### Claim at position 17 (depends on 2)

17: The split lens, as recited in claim 2, wherein said light shielding element has an annular shape and is made of opaque material applied on a surface portion of a lens of one of said first lens set and said second lens set for blocking light from passing through said surface portion of said lens covered by said light shielding element.

### Claim at position 18 (depends on 1)

18: A camera module, comprising:
said lens split as claimed in claim 1, and
at least one photosensitive unit, wherein an image is formed via a photoelectric conversion when light passes through said split lens to said photosensitive unit.

### Claim at position 19 (depends on 18)

19: An electronic apparatus, comprising:
