[0002] In recent years, with the rapid development of portable electronic devices such as smart phones and tablet computers, in addition to being an important communication device in people's daily lives, they are also widely used in various photography fields in daily life. Therefore, people's requirements for the photography function of portable electronic devices are getting higher and higher, especially when shooting objects with a wide field of view such as mountains and rivers. In this case, wide-angle lenses are favored by more and more mobile phone manufacturers and consumers.

[0003] Compared with ordinary lenses, wide-angle lenses have a longer depth of field, can clearly image within a relatively large range, and have a wider viewing angle, which can obtain a larger viewing range within a limited range. In addition, the lens has a stronger sense of perspective, and the photos taken by it emphasize the contrast between the size of the near and far views, thus creating a strong perspective effect in the depth direction.

It should also be understood that terms (such as terms defined in commonly used dictionaries) should be interpreted as having the same meaning as their meaning in the context of the relevant technology, and will not be interpreted in an idealized or overly formal sense unless explicitly defined in this article.

[0085] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0086] The features, principles and other aspects of the present application are described in detail below.

[0087] The optical imaging lens according to an exemplary embodiment of the present application may include six lenses with optical power, namely a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens. These six lenses are arranged in sequence along the optical axis from the object side to the image side. There may be a spacing distance between any two adjacent lenses among the first lens to the sixth lens.

[0088] In the exemplary embodiment, the first lens may have optical power, its object side is concave, and its image side is convex; the second lens has optical power; the third lens has optical power, its object side is convex, and its image side is convex; the fourth lens has negative optical power, its object side is convex, and its image side is concave; the fifth lens has optical power, its image side is convex; the sixth lens has optical power, its object side is convex, and its image side is concave.

[0089] The optical imaging lens according to the present application may satisfy: Semi-FOV≥61° and DT11 / DT52≤1.1, where Semi-FOV is half of the maximum field of view angle of the optical imaging lens, DT11 is the maximum effective radius of the object side of the first lens, and DT52 is the maximum effective radius of the image side of the fifth lens.

[0090] By reasonably setting the object side of the first lens to be concave and the image side to be convex, setting the object side of the third lens to be convex, controlling the fourth lens to have negative optical power and setting its object side to be convex, the optical imaging lens of the present application has a larger field of view angle, a wider shooting field of view, and can show a relatively large clear range.

[0091] The optical imaging lens according to the present application may satisfy: 1.3<ImgH×EPD / f<1.7, where ImgH is half of the diagonal length of the effective pixel area on the imaging surface of the optical imaging lens, f is the effective focal length of the optical imaging lens, and EPD is the entrance pupil diameter of the optical imaging lens.

[0092] In the exemplary embodiment, the optical imaging lens according to the present application may satisfy, -0.7<f / f4<1.2, where f is the effective focal length of the optical imaging lens and f4 is the effective focal length of the fourth lens. By reasonably controlling the focal length of the fourth lens, the sensitivity of the fourth lens can be reduced.

[0093] In the exemplary embodiment, the optical imaging lens according to the present application may satisfy: -1<DT12 / R2<0, where DT12 is the maximum effective radius of the image side of the first lens and R2 is the curvature radius of the image side of the first lens. By reasonably controlling the ratio of the maximum effective radius of the image side of the first lens to its curvature radius within a reasonable range, the processing difficulty can be reduced.

[0094] In an exemplary embodiment, the optical imaging lens according to the present application can satisfy: 0 < f3 / (R5 + R6) < 0.6, where R5 is the curvature radius of the object side surface of the third lens, R6 is the curvature radius of the image side surface of the third lens, and f3 is the effective focal length of the third lens. By reasonably controlling the curvature radius of the object side surface of the third lens, the curvature radius of its image side surface, and the effective focal length, it is possible to facilitate the control of the incident and exit angles of off-axis field light rays and increase the matching with the photosensitive element and the band-pass filter.

[0095] In an exemplary embodiment, the optical imaging lens according to the present application can satisfy: -1.2 < R1 / f < -0.8, where R1 is the curvature radius of the object side surface of the first lens and f is the effective focal length of the optical imaging lens. By reasonably controlling the ratio of the curvature radius of the object side surface of the first lens to the effective focal length of the optical imaging lens within a reasonable range, it is beneficial for the optical system to better match the chip CRA.

[0096] In an exemplary embodiment, the optical imaging lens according to the present application can satisfy: 0 < SAG52 / (SAG52 + SAG51) < 0.7, where SAG52 is the axial distance between the intersection of the image side surface of the fifth lens and the optical axis and the vertex of the effective radius of the image side surface of the fifth lens, and SAG51 is the axial distance between the intersection of the object side surface of the fifth lens and the optical axis and the vertex of the effective radius of the object side surface of the fifth lens. By controlling the axial distance between the intersection of the image side surface of the fifth lens and the optical axis and the vertex of the effective radius of the image side surface of the fifth lens, and the axial distance between the intersection of the object side surface of the fifth lens and the optical axis and the vertex of the effective radius of the object side surface of the fifth lens, it is possible to avoid the fifth lens from being too curved, reduce the processing difficulty, and at the same time make the assembly of the optical imaging lens group more stable.

[0097] In an exemplary embodiment, the optical imaging lens according to the present application can satisfy: 0.2 < T56 / CT6 < 0.95, where CT6 is the central thickness of the sixth lens on the optical axis and T56 is the air gap between the fifth lens and the sixth lens on the optical axis. By reasonably distributing the air gaps of the optical imaging lens group, it is possible to ensure the processing and assembly characteristics, and avoid problems such as interference between the front and rear lenses during the assembly process due to too small a gap. At the same time, it is beneficial to slow down the light deflection, adjust the field curvature of the optical imaging lens, reduce the sensitivity, and thus obtain better imaging quality.

[0098] In an exemplary embodiment, the optical imaging lens according to the present application can satisfy: 0.2 < CT6 / ET6 < 0.8, where CT6 is the central thickness of the sixth lens on the optical axis and ET6 is the edge thickness of the sixth lens. By reasonably controlling the ratio range of CT6 and ET6, it is possible to reduce the processing difficulty of the lens, and at the same time reduce the angle between the chief ray and the optical axis when it enters the image plane, and improve the relative illumination of the image plane.

[0099] In an exemplary embodiment, the optical imaging lens according to the present application may satisfy: -1.3 < R7 / f4 < -0.2, where R7 is the curvature radius of the object side surface of the fourth lens, and f4 is the effective focal length of the fourth lens. By controlling the curvature radius of the object side surface and the effective focal length of the fourth lens, it is beneficial to control the incident angle of off-axis field light on the imaging surface and increase the matching with the photosensitive element and the band-pass filter.

[0100] In an exemplary embodiment, the optical imaging lens according to the present application may satisfy: 0.5 < CT3 / CT5 < 1.8, where CT3 is the central thickness of the third lens on the optical axis, and CT5 is the central thickness of the fifth lens on the optical axis. By reasonably distributing the central thickness of the third lens and the central thickness of the fifth lens, the size of the rear end of the optical imaging lens can be effectively reduced to ensure the miniaturization of the lens, which is helpful for the assembly of the optical imaging lens.

[0101] In an exemplary embodiment, the optical imaging lens according to the present application may satisfy: 0 < T12 / T23 < 0.7, where T12 is the air gap between the first lens and the second lens on the optical axis, and T23 is the air gap between the second lens and the third lens on the optical axis. By reasonably distributing the ratio between the axial spacing distance between the first lens and the second lens and the axial spacing distance between the second lens and the third lens, it is beneficial to improve the lens assembly stability of the optical imaging lens and the consistency of mass production, and is beneficial to improving the production yield of the optical imaging lens.

[0102] In an embodiment of the present application, at least one of the lens surfaces of each lens is an aspherical surface, that is, at least one of the lens surfaces from the object side surface of the first lens to the image side surface of the sixth lens is an aspherical surface. The characteristic of an aspherical lens is that the curvature changes continuously from the center of the lens to the periphery of the lens. Different from a spherical lens with a constant curvature from the center of the lens to the periphery of the lens, an aspherical lens has better curvature radius characteristics and has the advantages of improving distortion aberration and astigmatism aberration. After using an aspherical lens, it is possible to eliminate as much as possible the aberration that appears during imaging, thereby improving the imaging quality. Optionally, at least one of the object side surface and the image side surface of each of the first lens, the second lens, the third lens, the fourth lens, the fifth lens, and the sixth lens is an aspherical surface. Optionally, both the object side surface and the image side surface of each of the first lens, the second lens, the third lens, the fourth lens, the fifth lens, and the sixth lens are aspherical surfaces.

[0103] However, those skilled in the art should understand that, without departing from the technical solution claimed in the present application, the number of lenses constituting the optical imaging lens can be changed to obtain the various results and advantages described in this specification. For example, although six lenses are described as an example in the embodiments, the optical imaging lens is not limited to including six lenses. If necessary, the optical imaging lens may also include other numbers of lenses.

[0104] Specific embodiments of the optical imaging lens applicable to the above-mentioned embodiments are further described below with reference to the accompanying drawings.

[0108] The first lens E1 has negative optical power, and its object side surface S1 is concave, and its image side surface S2 is convex. The second lens E2 has negative optical power, and its object side surface S3 is convex, and its image side surface S4 is concave. The third lens E3 has positive optical power, and its object side surface S5 is convex, and its image side surface S6 is convex. The fourth lens E4 has negative optical power, and its object side surface S7 is convex, and its image side surface S8 is concave.

The filter E7 has an object side surface S13 and an image side surface S14. The light from the object passes through each surface S1 to S14 in sequence and is finally imaged on the imaging surface S15.

[0112] Table 1

[0113] In this example, the total length TTL of the optical imaging lens (i.e., the distance from the object-side surface S1 of the first lens E1 to the imaging surface S15 of the optical imaging lens on the optical axis) is 3.63 mm, and half of the diagonal length of the effective pixel area on the imaging surface S15 of the optical imaging lens ImgH is 5.40 mm. The total effective focal length f of the optical imaging lens is 2.22 mm, half of the maximum field of view Semi-FOV of the optical imaging lens is 61°, and the aperture value Fno is 2.28.

[0114] In Example 1, the object side surface and the image side surface of any lens among the first lens E1 to the sixth lens E6 are both aspherical surfaces, and the surface shape x of each aspherical lens can be defined by but not limited to the following aspherical surface formula:

[0115]
