Abstract

The present disclosure discloses a camera lens assembly. The camera lens assembly includes a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens, which all have refractive power and are sequentially arranged from an object side to an image side along an optical axis. The first lens and the sixth lens have negative refractive power; the third lens and the fifth lens have positive refractive power; at least one of the first lens to the sixth lens has a non-rotationally symmetric aspheric surface; wherein tan(FOVx/2)*tan(FOVy/2)<2.0, where FOVx is a full field-of-view of the camera lens assembly in an X-axis direction and FOVy is a full field-of-view of the camera lens assembly in a Y-axis direction, and values of FOVx and FOVy are different.

First claim

What is claimed is:

1. A camera lens assembly, comprising a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens, which all have refractive power and are sequentially arranged from an object side to an image side along an optical axis, wherein,
the first lens and the sixth lens have negative refractive power;
the third lens and the fifth lens have positive refractive power;
at least one of the first lens to the sixth lens has a non-rotationally symmetric aspheric surface; and
wherein tan(FOVx/2)*tan(FOVy/2)<2.0, where FOVx is a full field-of-view of the camera lens assembly in an X-axis direction and FOVy is a full field-of-view of the camera lens assembly in a Y-axis direction, and values of FOVx and FOVy are different, wherein
an object-side surface of the second lens is a convex surface, an image-side surface of the second lens is a concave surface, and an object-side surface of the fourth lens is a concave surface.

2. The camera lens assembly according to claim 1 , wherein
√{square root over ( IH x 2 +IH y 2 )}≤6.0 mm,

where, IHx is an image height of the camera lens assembly in an X-axis direction, and IHy is an image height of the camera lens assembly in a Y-axis direction.

3. The camera lens assembly according to claim 1 , wherein 3.0<fy2/fy3<5.0, where fy2 is an effective focal length of the second lens in a Y-axis direction and fy3 is an effective focal length of the third lens in the Y-axis direction.

4. The camera lens assembly according to claim 1 , wherein −0.5<fx5/fx6<0, where fx5 is an effective focal length of the fifth lens in an X-axis direction and fx6 is an effective focal length of the sixth lens in the X-axis direction.

5. The camera lens assembly according to claim 1 , wherein −0.5<fy1/fy2<0, where fy1 is an effective focal length of the first lens in a Y-axis direction and fy2 is an effective focal length of the second lens in the Y-axis direction.

6. The camera lens assembly according to claim 1 , wherein an object-side surface of the first lens is a concave surface; and
wherein −1.0<fy/R1<0, where fy is an effective focal length of the camera lens assembly in a Y-axis direction and R1 is a radius of curvature of the object-side surface of the first lens.
