Embodiment 1

[0050] First refer to Figure 1 to Figure 5 An imaging lens group according to Embodiment 1 of the present application will be described.

[0051] figure 1 It is a schematic diagram showing the structure of the camera lens group in Embodiment 1. Such as figure 1 As shown, the camera lens group includes 5 lenses. The five lenses are the first lens E1 with object side S1 and image side S2, the second lens E2 with object side S3 and image side S4, the third lens E3 with object side S5 and image side S6, and the third lens E3 with object side S5 and image side S6. A fourth lens E4 with side S7 and image side S8 and a fifth lens E5 with object side S9 and image side S10. The first lens E1 to the fifth lens E5 are sequentially arranged from the object side to the image side of the imaging lens group. The centering group includes a first lens and a second lens, and the fixed group includes a third lens, a fourth lens and a fifth lens. The centering group is adjustable in the di...

[0073] Refer to the following Figure 6 to Figure 10 An imaging lens group according to Embodiment 2 of the present application will be described.

[0074] Image 6 It is a schematic diagram showing the structure of the camera lens group in Embodiment 2. Such as Image 6 As shown, the camera lens group includes 6 lenses. The six lenses are the first lens E1 with object side S1 and image side S2, the second lens E2 with object side S3 and image side S4, the third lens E3 with object side S5 and image side S6, and the third lens E3 with object side S5 and image side S6. A fourth lens E4 with a side S7 and an image side S8, a fifth lens E5 with an object side S9 and an image side S10, and a sixth lens E6 with an object side S11 and an image side S12. The first lens E1 to the sixth lens E6 are sequentially arranged from the object side to the image side of the imaging lens group. The centering group includes a first lens, a second lens and a third lens, and the fixed group in...

Embodiment 3

[0094] Refer to the following Figure 11 to Figure 15 An imaging lens group according to Embodiment 3 of the present application will be described.

[0095] Figure 11 It is a schematic diagram showing the structure of the camera lens group in Embodiment 3. The camera lens group includes a first lens E1 , a second lens E2 , a third lens E3 , a fourth lens E4 , a fifth lens E5 and a sixth lens E6 from the object side to the image side. The centering group includes a first lens, a second lens and a third lens, and the fixed group includes a fourth lens, a fifth lens and a sixth lens. The centering group is adjustable in the direction perpendicular to the optical axis.

[0096] The first lens E1 may have positive refractive power, and its object side S1 may be convex, and its image side S2 may be concave.

[0097] The second lens E2 may have negative refractive power, and its object side S3 may be convex, and its image side S4 may be concave.

[0098] The third lens E3 may h...

Abstract

The invention discloses a camera lens assembly. The camera lens assembly sequentially comprises an aligning assembly and a fixing assembly from an object side to an image side, wherein the aligning assembly has positive refractive power and at least comprises a lens; the lens which is the closest to the object side in the aligning assembly has positive refractive power; the fixing assembly has focal power and at least comprises a lens; the lens which is the closest to the image side in the fixing assembly has negative refractive powder; and the effective focal length fa of the aligning assembly and the effective focal length f of the camera lens assembly meet the following formula: 0.6< fa / f< 2.0. The camera lens assembly comprises the automatic aligning assembly and the fixing assembly; the aligning function can be fulfilled in a grouped manner, so that the process yield of a module is improved, and the AF time is shortened.

Description

technical field [0001] The invention relates to a camera lens group, in particular to a camera lens group of an automatic core adjustment group. Background technique [0002] At present, the photosensitive elements commonly used in optical systems include photosensitive coupling elements and complementary metal oxide semiconductor elements. With the improvement of the performance and size reduction of these commonly used photosensitive elements, corresponding requirements are put forward for the high imaging quality and miniaturization of the matching camera lens. At the same time, people have higher and higher requirements for the imaging quality of portable electronic products, and electronic products such as mobile phones and tablet computers will become thinner and smaller, which also requires high imaging quality and miniaturized camera lenses. [0003] The conventional high-pixel lens adopts the module core adjustment technology, and the entire camera lens needs to be...
