Technical Field

[0001] This application relates to the field of optical imaging technology, and particularly to an optical lens, a camera module, and an electronic device. Background Art

[0002] In recent years, with the rapid development of optical imaging technology, users' requirements for the imaging quality of electronic devices have increased significantly. Currently, the five-piece optical lens is still the mainstream configuration of electronic devices. However, its imaging quality has become difficult to meet users' needs for high-quality imaging. In contrast, the seven-piece optical lens can significantly improve the optical resolution by increasing the number of lenses, thereby improving the imaging resolution and clarity to meet users' needs for high-quality imaging. However, the increase in the number of lenses also leads to an increase in the total length and volume of the optical lens, which conflicts with the development trend of the thin and light of electronic devices. Summary of the Invention

[0003] In view of the above, it is necessary to provide an optical lens, a camera module, and an electronic device to meet the miniaturization design while ensuring the imaging quality.

[0004] In the first aspect of the embodiments of this application, an optical lens is provided, which has seven lenses with refractive power. Along the optical axis from the object side to the image side, it successively includes: a first lens with positive refractive power, whose object side surface is convex near the optical axis, and whose image side surface is concave near the optical axis; a second lens with positive refractive power, whose object side surface is convex near the optical axis, and whose image side surface is convex near the optical axis; a third lens with negative refractive power, whose object side surface is concave near the optical axis; a fourth lens with positive refractive power, whose object side surface is concave near the optical axis, and whose image side surface is convex near the optical axis; a fifth lens with positive refractive power, whose object side surface is convex near the optical axis, and whose image side surface is concave near the optical axis; a sixth lens with refractive power, whose object side surface is convex near the optical axis, and whose image side surface is concave near the optical axis; a seventh lens with negative refractive power, whose object side surface is convex near the optical axis, and whose image side surface is concave near the optical axis; the optical lens satisfies the following relationship: 0.95 < TTL / ImgH < 1.1; where TTL is the distance from the object side surface of the first lens to the imaging surface of the optical lens on the optical axis, and ImgH is half of the image height corresponding to the maximum field angle of the optical lens.

[0005] The above optical lens is configured such that the first lens has a positive refractive power, with its object side being convex near the optical axis and its image side being concave near the optical axis, which is conducive to the incidence and convergence of light; the second lens has a positive refractive power, with its object side being convex near the optical axis and its image side being convex near the optical axis, and the second lens cooperates with the first lens to correct the spherical aberration generated by the optical lens; the third lens has a negative refractive power, with its object side being concave near the optical axis, which helps to reduce the angle of the chief ray incident from the front lens; the fourth lens has a positive refractive power, with its object side being concave near the optical axis and its image side being convex near the optical axis, and the fourth lens cooperates with the third lens to correct the astigmatism generated by the optical lens; the fifth lens has a positive refractive power, with its object side being convex near the optical axis and its image side being concave near the optical axis, and the fifth lens cooperates with the fourth lens to correct the spherical aberration, astigmatism, field curvature and distortion generated by the optical lens; the sixth lens has a refractive power, with its object side being convex near the optical axis and its image side being concave near the optical axis, and the sixth lens cooperates with the fifth lens to correct the coma generated by the optical lens; the seventh lens has a negative refractive power, with its object side being convex near the optical axis and its image side being concave near the optical axis, which helps to correct the field curvature generated by the optical lens, thereby ensuring the imaging quality of the optical lens and reducing the manufacturing difficulty of each lens in the optical lens.

[0006] Furthermore, by setting the optical lens to satisfy 0.95 < TTL / ImgH < 1.1, and reasonably configuring the range of TTL / ImgH, it is conducive to making the optical lens adapt to high-pixel image sensors, improving the resolution of the optical lens, and having more advantages when shooting scenes with medium focal distances. At the same time, by reasonably configuring the range of TTL / ImgH, the optical lens is limited to have a smaller overall optical length, making the optical lens have an ultra-thin characteristic, which is conducive to the miniaturized design of the optical lens.

[0007] In the second aspect of the embodiments of the present application, a camera module is provided, including: the above optical lens; and an image sensor disposed on the image side of the optical lens.

[0033] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0034] Please see Figure 1This application provides an optical lens 100 comprising seven refractive lenses, arranged sequentially along the optical axis O from the object side to the image side: a first lens L1, a second lens L2, a third lens L3, a fourth lens L4, a fifth lens L5, a sixth lens L6, and a seventh lens L7. During imaging, light rays enter sequentially from the object side of the first lens L1 through the first lens L1, second lens L2, third lens L3, fourth lens L4, fifth lens L5, sixth lens L6, and seventh lens L7, ultimately forming an image on the imaging plane IMG of the optical lens 100. The first lens L1 has positive refractive power, the second lens L2 has positive refractive power, the third lens L3 has negative refractive power, the fourth lens L4 has positive refractive power, the fifth lens L5 has positive refractive power, the sixth lens L6 has refractive power, and the seventh lens L7 has negative refractive power. The object-side surface S1 of the first lens L1 is convex near the optical axis O, and the image-side surface S2 of the first lens L1 is concave near the optical axis O; the object-side surface S3 of the second lens L2 is convex near the optical axis O, and the image-side surface S4 of the second lens L2 is convex near the optical axis O; the object-side surface S5 of the third lens L3 is concave near the optical axis O; the object-side surface S7 of the fourth lens L4 is concave near the optical axis O, and the image-side surface S8 of the fourth lens L4 is concave near the optical axis O. The object-side surface S9 of the fifth lens L5 is convex near the optical axis O, and the image-side surface S10 of the fifth lens L5 is concave near the optical axis O; the object-side surface S11 of the sixth lens L6 is convex near the optical axis O, and the image-side surface S12 of the sixth lens L6 is concave near the optical axis O; the object-side surface S13 of the seventh lens L7 is convex near the optical axis O, and the image-side surface S14 of the seventh lens L7 is concave near the optical axis O.

[0035] The above optical lens 100 is configured such that the first lens L1 has a positive refractive power. Its object side S1 is convex near the optical axis O, and its image side S2 is concave near the optical axis O, which is conducive to the incidence and convergence of light. The second lens L2 has a positive refractive power. Its object side S3 is convex near the optical axis O, and its image side S4 is convex near the optical axis O. The second lens L2 and the first lens L1 cooperate to correct the spherical aberration generated by the optical lens 100. The third lens L3 has a negative refractive power. Its object side S5 is concave near the optical axis O, which is beneficial to reducing the angle of the chief ray incident from the front lens. The fourth lens L4 has a positive refractive power. Its object side S7 is concave near the optical axis O, and its image side S8 is convex near the optical axis O. The fourth lens L4 and the third lens L3 cooperate to correct the astigmatism generated by the optical lens 100. The fifth lens L5 has a positive refractive power. Its object side S9 is convex near the optical axis O, and its image side S10 is concave near the optical axis O. The fifth lens L5 and the fourth lens L4 cooperate to correct the spherical aberration, astigmatism, field curvature, and distortion generated by the optical lens 100. The sixth lens L6 has a refractive power. Its object side S11 is convex near the optical axis O, and its image side S12 is concave near the optical axis O. The sixth lens L5 and the fifth lens L5 cooperate to correct the coma generated by the optical lens 100. The seventh lens L7 has a negative refractive power. Its object side S13 is convex near the optical axis O, and its image side S14 is concave near the optical axis O, which is beneficial to correcting the field curvature generated by the optical lens 100, thereby ensuring the imaging quality of the optical lens 100 and reducing the manufacturing difficulty of each lens in the optical lens 100.

[0036] Furthermore, the optical lens 100 satisfies the following relationship: 0.95 < TTL / ImgH < 1.1; for example, TTL / ImgH can be 0.951, 0.96, 0.97, 0.98, 0.99, 1.0, 1.01, 1.02, 1.03, 1.04, 1.05, 1.06, 1.07, 1.08, 1.09, 1.099, etc. More preferably, 0.98 < TTL / ImgH < 1.05. Here, TTL is the distance from the object side S1 of the first lens L1 to the imaging surface of the optical lens 100 on the optical axis O, and ImgH is half of the image height corresponding to the maximum field angle of the optical lens 100. By setting the optical lens 100 to satisfy the above relationship and reasonably configuring the range of TTL / ImgH, it is beneficial for the optical lens 100 to adapt to high-pixel image sensors, improve the resolution of the optical lens 100, and have more advantages when shooting scenes with medium focal distances. At the same time, by reasonably configuring the range of TTL / ImgH, the optical lens 100 is limited to have a smaller overall optical length, making the optical lens 100 have an ultra-thin characteristic, which is beneficial for the optical lens 100 to achieve miniaturized design.

[0037] In some embodiments, when the optical lens 100 is applied to electronic devices such as smartphones and tablets, the materials of the first lens L1, second lens L2, third lens L3, fourth lens L4, fifth lens L5, sixth lens L6, and seventh lens L7 can be plastic to reduce the overall weight of the optical lens 100. Furthermore, it is understood that when the optical lens 100 is applied to electronic devices such as in-vehicle devices and dashcams, the materials of the first lens L1, second lens L2, third lens L3, fourth lens L4, fifth lens L5, sixth lens L6, and seventh lens L7 can all be glass, thereby enabling the optical lens 100 to achieve good optical performance while reducing the impact of temperature on the lenses. Of course, among the multiple lenses of the optical lens 100, some lenses can be made of glass, and some lenses can be made of plastic, thereby ensuring that the impact of temperature on the lenses is reduced to achieve better imaging results, while also reducing the processing cost and weight of the lenses, thus reducing the processing cost and overall weight of the optical lens 100.

[0038] In some embodiments, spherical lenses are considered to have the advantages of simple manufacturing process and low production cost, and can facilitate flexible design of lens surface shape, thereby improving the imaging resolution of optical lens 100. Aspherical lenses allow for more flexible design of the object side or image side of the lens, enabling the lens to effectively solve problems such as unclear imaging, distorted field of view, or narrow field of view even when the lens is small and thin. Furthermore, optical lens 100 does not need to set too many lenses to achieve good image quality, which is beneficial for shortening the length of optical lens 100. Based on this, the first lens L1, second lens L2, third lens L3, fourth lens L4, fifth lens L5, sixth lens L6, and seventh lens L7 can be aspherical lenses. This aspherical design not only improves the manufacturability of each lens and facilitates surface design, but also allows for more flexible design of the object-side or image-side surfaces. This enables each lens to effectively address issues such as unclear imaging, distorted field of view, or narrow field of view even with smaller and thinner dimensions. Furthermore, the optical lens 100 achieves good image quality and high resolution without requiring an excessive number of lenses, while also reducing the length of the optical lens 100. It is understood that in other embodiments, the surfaces of each lens in the optical lens 100 can be entirely spherical, entirely aspherical, or any combination of spherical and aspherical surfaces, depending on actual needs. Therefore, this embodiment does not impose specific limitations.

[0039] In some embodiments, the optical lens 100 further includes an aperture STO. The aperture STO can be an aperture stop and / or a field stop. For example, the aperture STO can be an aperture stop, or the aperture STO can be a field stop, or the aperture STO can be both an aperture stop and a field stop. In this embodiment, the aperture STO is disposed on the object side surface S1 of the first lens L1. It can be understood that in other embodiments, the aperture STO can also be disposed between other lenses and can be adjusted according to actual situations. This embodiment does not make specific limitations in this regard.

[0040] In some embodiments, the optical lens 100 further includes an IR filter IR. The IR filter IR is disposed between the image side surface S14 of the seventh lens L7 and the imaging surface IMG of the optical lens 100. Optionally, the IR filter IR can be an infrared cut-off filter to filter out infrared light and pass visible light, making the imaging more in line with the visual experience of the human eye, thereby improving the imaging quality. In some other embodiments, the IR filter IR can be an infrared band-pass filter, which can filter out light of other bands such as visible light, allow infrared light to pass through, and reflect visible light to achieve infrared imaging of the optical lens 100, enabling the optical lens 100 to image in a low-light environment or special application scenarios and obtain good imaging quality. It can be understood that the IR filter IR can be made of plastic, or can be made of optical glass with a coating, or an IR filter of other materials, and can be selected according to actual needs. This embodiment does not make specific limitations in this regard.

[0093] The optical lens 100 of this embodiment will be described in detail below in combination with specific parameters.

[0094] The First Embodiment

[0095] The structural schematic diagram of the optical lens 100 disclosed in the first embodiment of the present application is as Figure 1 shown. The optical lens 100 includes a stop STO, a first lens L1, a second lens L2, a third lens L3, a fourth lens L4, a fifth lens L5, a sixth lens L6, a seventh lens L7, and a filter IR, which are sequentially arranged along the optical axis O from the object side to the image side.

[0096] The first lens L1 has a positive refractive power, the second lens L2 has a positive refractive power, the third lens L3 has a negative refractive power, the fourth lens L4 has a positive refractive power, the fifth lens L5 has a positive refractive power, the sixth lens L6 has a negative refractive power, and the seventh lens L7 has a negative refractive power.

[0097] The object-side surface S1 of the first lens L1 is convex near the optical axis O, and the image-side surface S2 of the first lens L1 is concave near the optical axis O; the object-side surface S3 of the second lens L2 is convex near the optical axis O, and the image-side surface S4 of the second lens L2 is convex near the optical axis O; the object-side surface S5 of the third lens L3 is concave near the optical axis O, and the image-side surface S6 of the third lens L3 is convex near the optical axis O; the object-side surface S7 of the fourth lens L4 is concave near the optical axis O, and the fourth... The image-side surface S8 of lens L4 is convex near the optical axis O; the object-side surface S9 of the fifth lens L5 is convex near the optical axis O, and the image-side surface S10 of the fifth lens L5 is concave near the optical axis O; the object-side surface S11 of the sixth lens L6 is convex near the optical axis O, and the image-side surface S12 of the sixth lens L6 is concave near the optical axis O; the object-side surface S13 of the seventh lens L7 is convex near the optical axis O, and the image-side surface S14 of the seventh lens L7 is concave near the optical axis O.

[0098] Specifically, the Y-radius in Table 1a refers to the radius of curvature of the object-side or image-side surface of the corresponding surface number at the optical axis O. The first value in the "Thickness" parameter column for the lens is the thickness of the lens on the optical axis O, and the second value is the distance from the image-side surface of the lens to the rear surface on the optical axis O. The value of the stop STO in the "Thickness" parameter column is the distance from the stop STO to the vertex of the rear surface (the vertex refers to the intersection of the surface and the optical axis O) on the optical axis O. By default, the direction from the object-side surface S1 of the first lens L1 to the image-side surface S14 of the seventh lens L7 is the positive direction of the optical axis O. When this value is negative, it indicates that the stop STO is set on the image side of the vertex of the rear surface. If the thickness of the stop STO is positive, the stop STO is on the object side of the vertex of the rear surface. It is understood that the units for the Y-radius, thickness, and effective focal length in Table 1a are all mm. Furthermore, the reference wavelength for the refractive index, Abbe number, and effective focal length of each lens in Table 1a is 555.0000 nm.

[0099] In the first embodiment, the object side and image side of each lens are aspherical. Table 1b gives the conic constant k and higher-order coefficients A4, A6, A8, A10, A12, A14, A16, A18, A20, A22, A24, A26, A28, and A30 that can be used for the aspherical mirrors in the first embodiment.
